after another group of migrants are rescued trying to make the journey from africa. the italian coast guard rescued 72 migrants from its boat shortly before it sank about 100 yards off the coast. in sicily about 100 migrants from ethiopia and syria arrived. italian authorities arrested two suspected traffickers on board. within the past week italian ships picked up nearly 10,000 migrants. 400 are believed to have died when a boat cap sized on monday. paul is in sicily with the latest. >>reporter: the flow of migrants from libya continues. the total is 93 people. the breakdown is 71 men, 19 women. one of whom is pregnant and three children too. there is one glimmer of good news and that is that we've spoke on the the coast guard saturday morning and they're telling us that they're not aware of any ongoing rescue operations that are continuing as we speak. it seems that there are no boats that are issuing may days right now. it would appear though that is a briefs are s arerespite because the weather here is nice. as far as other issues the prosecutor of this town is promising that he'll prosecute any traffickers. he says he's already started to prosecute some traffickers that have been arrested on the boats by the italian coast guard and he's promising more prosecutions will take place. and the other thing is the italian prime minister has met with president barack obama and the subject of the migration from north africa came up there. from the american point of view it was to do with the security concerns. the wave of migrants seeking safety has overwhelmed refugee centers in italy. other cities have budgeted more than $4 million to help look after them but spending that kind of money has residents angry. >>reporter: there's a storm on the way and not just in the literal sense. the migrants keep coming here to italy's affluent north. public money is being earmarked to house them. the people are not happy. >> this historic town has barely changed over the years but its population has, especially recently because like much of italy, it is struggling to cope with that huge number of migrants who keep arriving. and the thing about the north is that typically it's the more prosperous end of the country. there's a lot of manufacturing, a lot of industry, a lot of money here. but for the people in these parts, they say we have our own problems. we need that money to be spent on us not the migrants. on saturday this protest was organized by the northern league, an anti-immigrant party. it wants italians to stop the local governments using its cash to look after those new arrivals. >> italy's economy can't bear this situation. we're in a deep economic crisis. we should come first. the others second. it's not racism. the point is italy doesn't have the resources to take the hit. >>reporter: supporters cannot sign a petition quickly enough. >> it continues. there is a big problem of security. our wives and children can't work around this anymore. this is a big problem. >> too many are here. there is not enough space for everybody and not enough jobs. >>reporter: on the edge of town the migrants have their own space. this is a community segregated from a community. a tale of two towns. they've withstood countless battles over the centuries but not of this kind. it's surrounded by a mote cutting it off from the outside world. you can see the irony here. it can't keep people out anymore. the face of this place is changing. here are some numbers that really put this crisis into perspective perspective. this week the coast guard rescued 10,000 people. last year over 3,000 people drowned crossing the mediterranean sea. overall, 51,000 people fled their countries last year. the pope today calling on the world to wake up to the migrant crisis. during their first ever meeting between the pontiff and italy's new president, the pope praised the italian government's response and also called on europe and the international community to do more. >> it is clear that the proportions of this phenomenon require a much wider involvement. we must not tire in urging a broader commitment at a european and international level. >> italy's president echoed the pope's calls saying the european union must take action. the president of afghanistan says isil is responsible for today's deadly attack in gentleman loll badjalalabad jalalabad. >> many people died of their wounds. >>reporter: two other blasts around the same time targeted a shrine and another bank highlighting a difficult security situation. president ghani says groups affiliated with isil are to blame. >> today the taliban did not take responsibility. daish took responsibility. international terrorists are responsible. they're not our people. if you're african or muslim come stand with us. if not, this is a warning. >>reporter: ghani called this a new war. he asked afghans to unite against what he calls international terrorists. the attacks came as parliament approved all of ghani's cabinet picks. ghani says it will be a strong government able to implement his reforms. in iraq and syria, united states and its allies launched 20 air strikes against isil on friday. iraqi ground forces secured the country's largest oil refinely after heavy clashes with the group. this after they briefly took over a small part of the complex. thousands of those iraqi families have nothing more than the clothes on their backs. the islamic state fighters clashed with the iraqi troops in the capital. one of five teenagers arrested in ausa made a brief court appearance. he was charged with planning an attack during a war remembrance ceremony to be held next week. he'll remain in police custody while awaiting an upcoming court date. the prime minister says that terror threat in australia had escalated within the last six months today in the war in yemen, the saudi-led coalition made an agreement with local tribes to guard and control key oil fields. also saudi forces are blocking the country's ports. the moves are an attempt to keep the conflict from crossing the border into saudi arabia. >>reporter: according to the coalition spokesman, heavy weapons and artillery have been observed moving. this sun usual because the bulk of the fighting is happening right now in the center of yemen and other areas very far away. this is not a retreat according to the spokesman. it is rather a movement of troops and heavy artillery towards the saudi border. we've seen clashes happening every now and then across that line and we've seen saudi troops being killed there by the houthis. a spokesman talked about the death of one saudi soldier yesterday during clashes on the border. so there are fears now by the saudis that fresh clashes will happen fresh clashes by the houthis at the saudi border. and the main objective is to make sure the war on yemen doesn't spill over into their own territory. this is a tough situation where after more than three weeks of air strikes on the houthis, the houthi houthis are still there. new hampshire is full of republican presidential contends contendserscontends contenders right now. >> can you see me? can you understand me? >>reporter: the republican faithful in new hampshire cheering a growing list of candidates. >> i want to tell you what i want to talk 5b9. >>reporter: 19 of them appeared at the republican leadership summit trying to woo voters from 2016. >> i don't want a correlation on our side by any stretch of the imagination. >> i don't see it coming my way. >>reporter: to lesser known candidates candidates. >> president obama doesn't believe in america. he doesn't believe in the america i believe in and i don't think he bes in the america you believe in. >>reporter: although many attack hillary clinton. >> i could have sworn i saw hillary's van outside. [laughter]. >>reporter: a lot of criticism was also aimed at president obama. >> we see the obama administration engaging in what i believe is the most serious act of appeasement by an american president in history. >> we lived through a great depression jimmy carter we'll live through barack obama, i promise you. >>reporter: new hampshire is where the first primary will be held early next year. marco rubio talked about a fading american dream. >> why is this happening to the greatest nation in human history? it's because we have too many leaders trapped in the past. people who think it's still the 20th century. >>reporter: new jersey's governor has noted officially said he's running. >> figure out what he wants to hear tell it to you, and pray to god you don't remember what i said when i go and do the opposite opposite. okay. that's not who i am. >>reporter: although the new hampshire primary is still more than nine months away republicans are wasting no time to try to bring the state back to the gop column montana is on track to join 28 states by expanding medicaid to cover more low income people. democrats and republicans in both chamberings okayed the expansion bill and sent it to the governor today. the affordable care act attempted to expand medicate to all states. it was made optional in 2012 the future of the immigration laws was heard in federal appeals court on friday. 26 states came together to argue against the president's executive action. the outcome of the case -- jonathan martin reports from new orleans. >>reporter: it's a major test for president obama's executive action on immigration. several huh-uh documented migrant -- several hundred undocumented migrants rallied outside the federal court of appeals in new orleans. inside a panel of three judges heard oral arguments and soon will decide whether they will move forward or remain on hold. >> all the organizations here all of us in the street we believe it's going to touch the heart of these judges and win. >>reporter: in february a u.s. district judge in texas ordered a temporary injunction on the president's executive action after 26 states filed suit challenging it. at issue are deferred action programs that protect undocumented migrants who arrived in the u.s. as children and undocumented parents of u.s.-born children. >> i'm in the process of being deported right now. this would help me stay with my children. >>reporter: the texas solicitor general who says deferring deportation means a financial burden on states because they would be forced to spend more on law enforcemented, education, and healthcare. outside the court those in favor of the immigration move outnumbered those against but opponents were vocal as well. deborah smith travelled from mississippi. >> we built this country on the backs of immigrants. that's who we are. we have to -- we're also a nation of laws. >>reporter: but supporters remain optimistic. many realize a ruling in their favor may be tough as the fifth circuit court of appeals is considered the most conservative conservative circuit in the united states. it could be several days or even a couple of weeks before a final decision is made. when we return we're grading education in the u.s. a deeper look at why american students are lagging behind students in the rest of the world. plus in indiana, an outbreak of hiv appears to be getting worse and is china replacing the imf? the latest from the group's meeting in d.c. this weekend when we come back. in many parts of the country, students took tests this week that assessed their abilities against common core standards which detail what students should know in a variety of subjects at the end of each grade. for most schools this is only the first or second year for these standards but in many districts parents are letting their children opt out of the test. tonight in our deeper look segment we're grading education in the u.s. is common core helping or hurting students? has it become politicized for personal gain? and what can be done to ensure american students can catch up to their peers around the world. we begin with this report. >>reporter: since their debut in 2009 common core standards have become controversial. it was developed at the state level by the national governor's association and school officials. it is not mandatory. however, the obama administration later linked race to the top grants to the adapt adaptation to common core standards. year after year american students lag behind their peered in other industrialize nations in subjects like math reading, and science. >> our curriculum was a mile wide and an inch deep when you compare it to the curriculum in high performing countries. so in japan, they might spend a week an a half on a topic and here we would spend three days. it's not necessarily magic why more of their students learn it. >>reporter: the american educators who developed the common core standards said they took into account the highest international standards and evidence and expertise about educational backgrounds. but the teaching community and parents seem split on the merits. >> we are the only country that tests our children ever year and all the countries at the top of the international rankings do not test yearly. >>reporter: critics say standardize testing is too hard consumes too much classroom time forces educators to teach the test and encourages cheating. >> this thing was per vasivevasivepervasive. in new jersey the teacher's union recently released these ads. >> my kids only have a half a year of science and social studies to prepare for the test. >>reporter: across the country, numerous websites encourage parents to opt their kids out of testing. in new york reports that 15% of students didn't take exams this week putting the state at risk of losing federal funding for not reaching the 95% threshold. the state board of education wrote the real impact of opting out is that we lose the chance at both the state and the local level to learn about the progress of our students and their schools. that loss is immediate. it is permanent. common core and standardize testing is also becoming very politicized. louisiana's governor has done an about face. >> the federal government would like to assert control of our educational system and rush implementation of a one size fits all for setting standards that raises a lot of concerns. and in ohio gop is trying to stop funding for standardize testing. politically this could be a wise move for republicans. it sets up a game of chicken with the u.s. department of education who could make good on threats to withhold much needed money from students who have little say in the debate swirling around them. joining us to take a deeper look is an is assistant professor of urban education at how owe la university in loyola university in chicago. just convicted of falsifying student test results. how pervasive is this problem? >> this was pretty isolated to see this kind of cheating going on in such a grand scale in atlanta. we cannot condone it. cheating is wrong no matter the reason. you see there were a couple of other instances of this around the country but most teachers even under a lot of pressure with the no child left behind act and with this push did not resort to this kind of behavior. that's good because this behavior is not ethical. that said back then this all happened about five six, seven years ago, we had an accountability system that was not well designed and did not take into account where kids were starting from. if kids were coming into school way behind the accountability system ignored that. thankfully most states have moved to new systems that take that into account and when you combine that with new standards, you have a much smarter accountability system in place. >> it's not all that isolated. there are problems throughout 37 other states that we know of so it's not just a couple of cases here. >> we're talking about an education system of 50 million kids, 3 million teachers. so, sure there have been a few dozen cases where teachers were cheating on tests. relatively isolated. to be up front, there's a lot of people out there who are not big fans of these tests and i think what you just saw was that change is very hard. what we are trying to do is dramatically raise standards and expectations in this country. we've had a system where kids have come into school gotten great results and it's when they try to go to college or get a job when someone tells them you're in the ready, you don't have the skills you need to succeed so we're trying to be much more honest with kids and their families about what they need to do to get on track and that is hard. this message is hard for a lot of people to hear. >> all right. do you agree with mike here? >> no. >> do you think the pressures are too much for teachers and pushing them to this extreme? >> i do think the pressures are extreme. i do think that they are pushing teachers and educators to do things that are unethical especially because of the high stakes nature. it's not just the standardize testing itself. but everything tied to it. you may not be able to keep your job. we may close your school. and in a situation like that when people have families to support and a livelihood to maintain, i think that people make choices that may be none of us know what choice we would make if we were backed into a corner. so i actually don't agree with him. >> so in talking about common core yes, this is a controversial topic. let's talk about opting out. more and more parents allowing kids to skip the tests. one parent here in new york gave this reason. take a listen. >> we refuse to comply in a system that uses flawed tests to sort and punish teachers children, and schools. >> mike what's your reaction to hearing this parent call the common core type of standardize test flawed? >> well here's what's ironic parents and teachers have complained for years about the standardize tests and they're right. in the past the tests were low level fill in the blank kinds of testst which coming along with common core we're finally getting to these next generation tests. they're much more challenging and like the advanced placement exams people are familiar with. for this opt out movement to hit at the same time we're finally fixing what was a real problem moving to better exams is hard to understand. to parents i'm a public school parent, i understand that if i decide to use the public cools that comes with responsibilities, one of them is to allow my kids to take these tests so that the public can know how the kids are performing. that's a good deal for a free public education. >> so do you think the common core kind of testing is fixing the standardize testing problem we've had for years? >> >> i think it could be but i'm a little bit concerned about this idea that students taking the test is owed to the public. assessment is important and i think that teachers and schools need to know how their students are doing and where they are but to me it is very inappropriate to use test scores in order to make decisions about faculty and release that information to the public. i don't like the idea of public school children being used as pawns really in a game to remove educators. >> all right. let's look at the big picture now. we saw that out of 34 countries, the u.s. ranking is not looking good math reading, science. why are american students lagging so far behind? >> you know i can't really answer. i mean i guess i would start with there's probably a lot more that could happen in classrooms and schools. but i also add to that that what teachers and educators are being asked to do and especially in some of the most underresourced places around the country is just beyond what some of us can imagine. a bulk of my research focuses on philadelphia where in 2013 20 schools were closed and nurses and librarians and secretaries were laid off and class sized increased because of the closings. i think it's possible but i also think it's a lot. i would guess that that has something to do -- looks like we lost her there. let's bring mike back in here. mike the united states spends more money on public education per student than any other country. what are we doing wrong here? what are we spending our money on? >> that's right. and what's important to know is that our performance is immediate immediate yolkmediocre mediocre. other countries have that problem too. our affluent kids are not performing well either. this is a problem throughout our entire education system an not just in the toughest schools like those in philadelphia that dr. royal was just mentioning. >> how do we fix it? >> when we look at what's going on it comes down to we are not asking our young people to work hard enough when it comes to academics. when it comes to sports, extracurriculars extracurriculars, we're happy to have them work hard and hustle and compete. but when it comes to math and reading and science for some reason in this country we have this culture where we don't push them very hard and the kids tell us this. >> how are we not -- hold on -- how with we not pushing kids if grades 3 throughal they're taking standardize tests through the year working hard to pass those tests and we're oneover the only countries that does this? >> because this is brand new. okay. we've had the testing but the tests until now have been incredibly easy. they've been very easy to pass. you can pass these tests in the -- if you were at the 20th percentile in reading or math. finally we have tests that are challenging. standards that are high where we expect students to master the material. that's what is new. and now the hard work begins to change classroom practice and teachers are working hard at this and we're receiveseeing progress and movement and to ask our kids to work harder might longer school days or years. other places around the country, the countries doing very well academically, their kids work hard on math reading, science. there's not enough of that in the united states effort matters a lot. >> this conversation is controversial and politics takes an important role. democrats and republicans were split along party lines when talking about quote, unquote, the common core but change the language, call it standardize testing and that's something both parties support. take a look at that. so the problem with education is the policy behind it. what do you think about the politics of all this? >> i think the politics are very interesting. i am not someone who's completely opposed to common core but i'm also not totally for common core. i think that the conversations that common core has raised the bar for our educators and students and i'm all for raising the bar but i also recognize that curriculum doesn't do the teaching so there has to be investment in the educators themselves for the higher bar to be translated to our students and to give them the support they need to reach that. it's sad to me if there is this really significant curriculum sift in common core for it to be politicized. but, you know i'm kind of -- the conversation around this being sort of a national movement and doesn't take into account local context, that's real and valid and for years people haven't really trusted local educators to build their own curriculum and i think that's a problem. >> that one new york parent who's having her kids opt out of the standardize tests, she says why can't we use our regular report card system to see how the kids are doing. i can see their grades quizes test midterms throughout the year. why isn't that good enough mike? >> it's a great question. those are incredibly important and they need to continue. the problem going way back 20, 30 years, some teachers had higher standards than others. some kids were getting as and go to college and flunk out because they were not ready. we had a particular problem in our highest poverty ty areas where standards were not high enough. up next south africa's president is vowing to end a wave of attacks on migrants and a mysterious disease that kills people in less than 24 hours is killing people in nigeria. nigeria. >> balanced and job rich global economy. the imf and world bank are two of the most powerful institutions on earth but they're facing stiff competition from a new entity in china. >>reporter: 1944, the imf and world bank are created to bail out troubled economies and build up developing ones. founded by 44 nations, the u.s. had outside influence and still does. thanks to congressional foot dragging on reforms that would give more say to influential developing economies like china. the u.s. holds about 17% of voting power at the imf compared to about 4% for china. an imbalance echoed at the world bank. >> you have this perception and a reality that the u.s. is a key driver in the bank. i think that's because of there's been an absence of alternatives. >>reporter: until now. china is using its massive foreign exchange reserves to build alternatives to the imf and world bank. pouring billions of dollars into the inter-american and african development bank and joining forces last year with countries, brazil russia india, and south africa to found the new development bank. last month, beijing's growing influence hit home when more than 50 countries rushed to become members of the investment bank including u.s. allies washington tried to dissuade from joining. >> what is at stake is strategic influence in critical regions of the world. >>reporter: because of congressional penny pinching u.s.-dominated lenders like the world bank have failed to keep pace leaving china to fill in the breach . south africa's president is vowing to end attacks on migrant migrants migrants. six have already died. this week there was a heavy presence in south africa. rioters had built street barricades and burned tires and vehicles. here's more. >>reporter: he's come to inspect what's left of his shop. he came to south africa six years ago to try to earn money for his family in ethiopia. >> it's tough. >>reporter: he says his shop was attacked by people who accused migrant workers of taking their jobs saying they stole everything he had including his savings. >> i don't know. these people are coming and taking stuff, money clothes, shoes. everything gets taken. i have children. i have wife. to my people i support me. why kill me? you kill me i tell you, no fighting. >>reporter: his landlord says he's ashamed about what happened if the. >> criminality. nothing else. >>reporter: it's very obvious the level of poverty in this neighborhood here in johannesburg. people here have very real needs. it seems that he was the victim of opportunists. in nigeria, 17 people have died from a mysterious disease that broke out early this week. it killed the victims within 24 hours of them becoming ill. laboratory tests have so far ruled out ebola or any other virus. health officials and experts have since arrived in the southeast of nigeria. no new cases have been reported in the past 72 hours. it's not spread beyond the town. investigations into the disease are still ongoing. in columbia the peace process is at risk after 11 soldiers were killed in an ambush. the president of columbia responded with air raids in rebel camps. military escalation and public outrage risk bringing the process to an end. >>reporter: the soldiers were ambushed in this village as they slept. apparently surprised by an attack in the middle of the farc lateral cease fire. >> we were awoken by the explosions. i jumped from my bed, ran to my kids and we all piled in one corner where we could feel somewhat safer. >>reporter: days after the incident the signs of just how devastating the attack has been are here for everybody to see. holes in the ground where the grenades exploded or blood stains on the floor. even the boot belonging to one of the soldiers. and the fear for the people who live here that the war is back. the village is at the center of a drugs and weapons corridor. coka plants are easy to spot in the hills. after a recent military antidrug ground operation, the villagers have feared the rebels would retaliate. and they did. >> we had asked the soldiers a month ago to please move away. bombings will resume and bring more violence. we need the talks to succeed. it's easy for the people in the city to say war is the answer when we're the victims. people bring flowers for the dead soldiers. for some the attack has wiped out what little confidence there was. >> it's time to end the peace process. it's a big lie. we're just giving rebels space to kill our soldiers. the government appears to be committed to resolving the process but it's complicated. >> the problem is there are numerous armed groups moving about the country inflicting violence in different ways and it's extremely hard in a contest to avoid these kinds of encounters. >>reporter: both the government and farc have invested much in the process and say they want a final agreement. but military escalation and other attacks risk setting back a process that had looked so positive. after a shootout friday with 60 members of a drug cartel and the mexican army and police authorities announce they have arrested the leader of the notorious gulf cartel. the drug wars have claimed the lives of more than 100,000 people in the last eight years. when we return, bmw issues a recall. we'll have details. also a new warning from health officials about teen tobacco use. and indiana is seeing a spike in hiv cases. two dozen cases in just the past week. we'll explain. stay with us. stay with us. no questions asked. but some are questioning its effectiveness. >> health officials say fewer teenagers are smoking cigarettes but overall tobacco use among teens is up. >>reporter: victoria randolph picked up her first cigarette at the age of 16. today she prefers puffing on this. randolph is smoking an electronic cigarette. >> they have instagram pages and facebook pages and youtube channels that teach you have to build them and all this stuff like it's a whole, you know a culture. >>reporter: it's a battery powered nicotine infused vaporizer that is growing in pop ewe later among teenagers. before the e cigarette she was smoking a pack of cigarettes a day. do you feel different? >> i feel healthier. i don't have the cough anymore. i always felt like i smelled bad all the time. >>reporter: according to a report thursday by the cdc, the number of middle ah and high school students who tried e cigarettes raised 15%. e cigarette-cigarette the fda is considering imposing regulations on the nearly $2 billion industry. among them banning sales to anyone under 18. >> electronic cigarettes contain and deliver nicotine. it's very dangerous to the developing child and adolescent brain. parents should take no comfort in the fact that their kids are using an e-cigarette rather than burning cigarette because of the presence of nicotine. any product used by a teen is bad for the public health. >> i'm using it to quit not for the culture. i still am using it that way. >>reporter: although selling e-cigarettes to minors is banned in some states right now there's no banning of sales to children in u.s. a proposed rule by the fda this summer could change this. and they've been working on a plan to reign in the industry. they want to curb the sale to minors as well as expose ingredients ingredients on all e-cigarette products coming up an update on the man who flew his aircraft on the lawn of the capitol this week. his week. we have special live >> he's the only male northern white rhino left in the world. here's more on the effort to protect their future. >>reporter: at the 90,000 acre reserve in kenya, he's under protection 24 hours a day to try to provide a double layer of security where he can be safe from poachers but also roam freely. they're always on hand but are not with thumb every second of the day. they want them to enjoy a natural existence in the wild. poachers are chasing them for their horns. they'll go for as much as $24,000 on the black moth -- $240,000 on the black market. with that much money at stake, poachers are willing to put their own lives at risk. conservationists are removed his horn. still, poaching is a big threat to him, the last of his kind. right now, they're working toward artificial reproduction techniques to allow his line to continue. >> . it's not just happening to rhinos. it's happening to all sorts of species across the planet >> the man who flew his aircraft onto the capitol lawn is headed back to his home in florida. he says he pulled off the stunt to protest weak campaign finance laws. thanks for joining us here today. we'll see you back here at 11:00. e at 11:00. >> on the weekend edition of "america tonight": a university schooled. in our series, sex crimes in sport, "america tonight's" sarah hoye on the campus and the community shamed. >> there's also been banner headlines. this is rape capital. this is the rape campus. >> some students caulk on water they can do no wrong and can get away with murder almost, it
