consent, while california's yes means yes law is a game changer. ♪ and you are looking at live pictures of hong kong, where protesters are still filling the streets, defying beijing's call to disperse. it is 8:00 am tuesday morning there. and this video shot by a drone gives you an idea of how many people have been take part in these demonstrations. there's no official number but estimates are in the 10s of thousands. this is one of china's biggest challenges since the crackdown in the square 25 years. protesters have chanted in the streets. major highways and roads are being blocked. beiji beijing's attitude appears to be one of wait and see. >> reporter: protest leaders were worried if they didn't get enough numbers on the streets, they would be vulnerable to riot police. as the crowd swelled, it become clear that the worry was with the authorities. a mass booing at the effigy of hong kong's leader, seen as a pro beijing hate figure by these protesters. one of the most pop chants of the night has been see him resign. this was a movement celebrating its own success, on the very highway where the night before it was facing tear gas. on monday night, no gas, and hardly any police presence. >> given the fact they launched tear gas and pepper spray, i think people are quite prepared for both. i mean they knew what to expect. and they still have the courage to come out and tell the government what they want, and tell the world as well. hong kong people do want democracy. >> i think the hong kong people are [ inaudible ] wanting to a real democracy for our future. >> reporter: this night belonged to the protest movement. the next move is with hong kong and china authorities. rob mcbride, al jazeera, hong kong. journalist and activist tom moves to hong kong from england nine years ago. he is on the telephone tonight. what is the situation now? >> i'm here at the headquarters and there are still thousands of young people gathered. there are people are signs urging them to stay on until 8:00, 9:00 when the next shift will take over. people dressed in black, which is quite a contrast to sunday when people were dawning goggles and face masks and there ruz a cloud of tear gas hanging over the area. >> what do you expect to happen today? >> well, people -- they are late to rise and late to bed here in hong kong, and as the afternoon and evening wears on, more and more seem to come on to the streets, and i'm sure it will be the same tonight on the eve of back-to-back holidays, where i imagine there will be even larger crowds as the week goes on. >> what is the dynamic between protesters and police? >> well, it was a complete contrast. yesterday very jovial, very low profile, it was very tough to even find a police officer in the tens of thousands of people in three different areas of the city. they have obviously had a change of heart. on sunday it was pepper spray, tear gas, and quite an aggressive attempt to clear the area. >> do you get the sense that all of hong kong is behind this? or is this one group? >> i would say that how people feel about universal suffrage, one person, one vote, people are pretty unified. you have the student strikers who have somewhat combined with the occupy movement. that's a bit more controversial. they talk a lot about civil disobedience, in a tradition like nelson mandela. but now there is a sympathy in people caught up in the police action. >> all right. tom thank you very much. mainland china said the government plans to let the protest run its course, and the chinese foreign ministry warned not to let other countries interfere. >> reporter: china's leadership has been restrained in their response. but it's clear they think unnamed countries are behind the unrest. >> we oppose any country that interferes with china's internal affairs, and any country that supports the occupy movement in any way. >> reporter: the student-lead protests bring back uncomfortable memories of what happened in beijing more than 25 years ago. but what will china do if unrest worsens in hong kong where it has 6,000 soldiers. >> we don't need to go to the last step. it is very, very pragmatic, i would say to let the whole process run its due course, and in this process, i think people in hong kong will come to the realization that peace and stability are more precious than chaos and instability. >> reporter: but is this another hint of government thinking? the article says china's armed forces could restore order in hong kong. it appeared on the website of the global times newspaper, but has since been de -- deleted. on the streets of beijing most say they were unaware of what was happening in hong kong. >> i think they have a legal right to protest but occupying the city center is too aggressive. there must be outside forces behind this. >> reporter: strict media controls have been tightened. and the photo sharing service, instagram has now been blocked. china hopes the protesters will simply taper out, and insisting it will never give in to the protesters demands. a display of solidarity by students in taiwan. the island china regards as a breakaway province. its president spoke to al jazeera before the protests, insisting beijing must be prudent. >> translator: it's not only important to the people of hong kong. the people of taiwan are also watching. and tonight the white house is expressing support for democratic elections in hong kong, but is also urging caution. >> the united states urges the hong kong government to show restrain and the protesters to protest peacefully. >> for days people in hong kong have been fighting for what they say they were promised democratic rights. but this standoff goes beyond the clashes of this weekend, it stretches back 20 years. jonathan betz explains. >> for more than 150 years britain owned hong kong. but in 1997 it handed hock kong back to china. it is not a separate country but it does have its own government. it is ruled by a governor or chief executive, and has freedom of speech and protest. but the biggest promise was it would get universal suffrage that means everyone would get to vote. and for the first time people of hong kong could choose their own leader in a democratic election. something hong kong does not have right now. but a few months ago china released the white paper declaring china's central government has comprehensive jurisdiction over all local elections. that meant china would first screen the candidates so they would only vote for candidates approved by beijing. that sparked the protests we're seeing in hong kong. protests in favor of democracy in hong kong have been held around the world. this woman head the demonstration here in new york and is in our studio here tonight. welcome. >> thank you. >> you were at tiamem square, right? >> i was in hong kong when it happened. >> what does it feel like to you to be watching this today? >> 25 years ago that night, i was in hong kong, and so that's why i'm very worried at this moment, and hopefully that will not repeat. >> with these protests in new york what sort of message did you want to send to beijing. >> we wanted to see a message to not just beijing, but also the hong kong people and around the world that we strive for the truth in democracy and universal suffrage, and we support the protesters right now. >> when tienam square happened, was there anything like this? >> not exactly. it was peaceful marching, and we did send students up there -- or other politicians up there to help out, but not exactly like that. with this square of the protesting. >> this time tear gas. >> yes. >> clashes with police. >> yes. >> like you haven't seen before. >> no, never. >> what is going on? >> we -- we do not know. that is unexpected. when sunday morning, and someone called me saying tear gas, tear gas, i was surprised. and we never expect that will happen. we believed that this is really excessive police brutality to the protest people, and all of the students, which all these people are actually protesting in a peaceful way. >> so do you think these protests are going to go on or will beijing be able to shut it down. >> of course we hope that beijing or even the hong kong government the heard, the chief executive can engage in a dialogue with the students or the politician, the legislators right now, and go to the end and have a peaceful ending to this thing. we wouldn't want anything like -- >> what do the protesters want? >> we want true democracy and universal suffrage, the real one. >> and youdy beijing would be willing to give that to you? >> of course this is all our hope. this is a universal thing all have. why not hong kong? >> will these protests spread to china as well? >> it may, but beijing promised one country, two system, if that happens this will end basically. >> we're looking at these live pictures, and there are plenty of people out in the streets. it's very early this morning. do you have any sense of what is supposed to happen there? >> what i also learned from the news media, it's not just occupy there, but also in two different major tourist areas. and these are just the normal hong kong citizens and people coming out. >> so you sense this is just the beginning maybe? >> possibly. >> it's good to have you on the program. >> thank you so much. now to the latest in the fight against isil. strikes were concentrated near a town in syria. and isil artillery landed inside the country. >> reporter: more shelling in the syrian town. the attacks have intensified over the last few days. and it is also intensifying the anger on the turkish side of the border. many kurds have some to protest saying the government is doing nothing. >> translator: we're protesting because isil and the turkish government are collaborating against our people. if cabani falls we'll all take up arms to fight for it. >> reporter: the security forces here are taking no chances in a border area that is already extremely tense. turkish forces have pushed the protesters back up that hill, pushing them further and further away interest the border. mor -- mortar shells are also landing here. the turkish army has heavy presence here, but for now it has not responded. head a few kilometers east and you can see one of isil's bases. >> translator: we're afraid because we feel threatened. we're at risk. the turkish government should intervene. >> reporter: the president says he will step up his commitment to fight isil. by sundown on monday, a visible change in military positioning for the first time. these turkish tanks are now facing the town of cabani. coming up at the half hour. we'll have an extraordinary story. nick schifrin will talk with a defected isil fighter. new details on the unprecedented white house security breach from earlier this month. the army veteran accused of breaking into the executive mansion with a knife made it much farther inside than previously disclosed. mike viqueira is at the white house with more. >> it turns out the penetration of the white house was much worse than we were initially told. the first family has just lifted out from marine en route to camp david on the south. on the north, omar jumped the fans, ran along the fence line, was not brought down by any of the secret service dogs. he was not tackled or even by gunfire. walked inside the north, and apprehended just inside the doors we were told at the time, near the stairwell that leads up to the residence that the president and his family reside. it turns out it was much worse than that. gonzalez actually penetrated into the white house. he ran through the doors of the north portco, which were unlocked, took a left into the east room, then took a right, headed south through the east room and was finally tackled and apprehended just outside the green room which faces the south of the white house. it is an embarrassment to the secret service once thought to be an impregnant -- impregnantable force. one other item here it turns out gonzales overpowered at least one officer once inside the white house. an embarrassing revelation on top of everything else they have had to deal with recently. john? nike nike at the white house. tonight at 11:00 eastern time, retired secret service agent clint hill talked about training and proceed urs officers used to protect the president and the white house. coming up the ground breaking way california will define whether a sexual assault took place. and israel's prime minister, his fiery u.n. speech, answering allegations made by the leader of the palestinians. ♪ california's made history by becoming the first state to change its approach towards victims of sexual assault on college campuses. students will no longer have to prove they said no to sex to make a case they were assaulted. instead the question will be whether both sides said yes. melissa joins us with more. >> reporter: california has always had a tendency to be on the forefront of active legislation, and perhaps other states will take up similar bills like this one. it's called active consent, better known as yes means yes, and instead of focusing on when a women resists sex, rape, it moves the bar for what is appropriate by making sure both participants agree to sex. this shifts the burden when a person was: all public universities and any private university that receives funding from the state of california will now need to comply to this new law. >> frankly everyone finds it fearful to talk about rape. rape is scary. but we need to treat it as less about sex, and more about crime, and the disciplinary problem for universities. >> reporter: aerial and sophie, students at uc berkeley survived sexual assault, and have now become activists against sexual violence. >> it's nice to see there's state-wide attention, and state-wide action about it. so a lot of schools already have these policies, so it's not to see the governor is stepping up and saying we really need to codify this. >> this is a necessary but not sufficient part of achieving the kind of cultural change we have been fighting for. >> reporter: difficult to gauge student response, the people we talk to call this progress. >> especially as a student i think it's very important that this is discussed. and a berkeley here we're trying to talk about enthusiastic consent, and this is in conjunction with that. >> reporter: but even the supporters admit this law may be difficult to enforce. >> i don't think the enforcement is going to be there. i can't see how they would do it. >> reporter: in addition the law says that universities and colleges must provide counselors for victims of sexual assault, and also training for on-campus investigators. up until now colleges and universities set up their own boards. sometimes these are faculty with no training at all. in addition, in-coming freshman will have orientation on sexual assault and what consent means. john. >> melissa thank you. sophie who was in that piece is a aco cofounder of this bill. does this bill go far enough? >> well, there is still more we can do. but we're trying to change a cultural shift. and this is a really important step forward. >> why is affirmative consent so necessary? >> yeah, so affirmative consent really shifts the burden from being on the survivor to prove they said no, so in a lot of instances, there are drugs involved or alcohol involved that is intentionally used against students in order to take advantage of them. and by having an affirmative consent structure, now the structure is in place so survivors who were taken advantage of, will have the ability to hold their perpetrators accountable too. >> that's because they -- if they were under the influence -- explain that to me. >> sure. >> if they were under the influence in both cases, isn't it still a problem making this case? >> so the burden is on the perpetrator with the affirmative consent standard. it is saying the survivor, if they didn't say yes, then that -- in that case the perpetrator can be held responsible for that. the issue is that a lot of the time survivors don't say anything. a lot of the time they are too incapacitated or have been purposefully drugged. it's usually not about a miscommunication. research has shown a lot of the times, perpetrators are intern shunnally doing this. it's not as if they didn't know. >> i mean i -- >> this takes it -- >> i don't want to belabor the point, but if a perpetrator will lie about whether or not the survivor said no, why wouldn't the perpetrator lie about whether or not the survivor said yes? >> sure. that's the reason why this bill does this change this conversation, is that it's essentially saying if the survivor says that they didn't say yes, then that is still -- then you can be found responsible for that. so it's not necessarily accurate to say that a perpetrator would lie about whether or not a survivor said yes, it would be -- the burden would be determined by the survivor. that -- that is the purpose of the bill is that it is supposed to be shifting the bill from being on the shoulders of the survivor. >> sophie does this really change the culture, though? >> i think it does. i lead a mini workshop over the weekend, outside of party where i asked students to tell me what consent means for them. and a lot of time students hadn't really thought about it before. but i suggested to them, what if you just ask your partner, is this okay? and then students really -- their perspectives really changed in that moment. i -- i could tell that students hadn't thought about this before, and were really intrigued by the idea of just simply asking, and multiple students came up to me afterwards and said thank you so much for doing this. i hadn't thought about it before. so i think the educational component is really important to. and that's part of why this bill has been really successful, because it has generated this public dialogue, changing the conversation from no means no to yes means yes. >> clearly you and many of your friends have worked to change the conversation. sophie, good to see you. thank you very much. >> thank you. still ahead, fighting for isil, why one man joined

said the u.s. underestimated isil. and the white house tried to clarify his statements today. mike viqueira has more. >> reporter: criticism on the president's comments last night. the director of national intelligence had said months before that that is in fact what happened. the intelligence community basically did not see this coming. president obama endorsed that view, and that brought a storm of criticism accusing the president of not taking responsibility. josh earnest defended the president and explained what he meant. >> i think the president was pretty clear both then as he was back in august, that nobody predicted the speed and pace with which isil would advance across the syrian border with iraq, and make dramatic gains across the countryside in a way that allowed them to hold large chunks of territory. >> the president added and the intelligence community agrees, the ability of the iraqi army was overestimated as was its willingness to fight the terrorist group. all this week nick schifrin is reporting from the syrian/turkey border on isil's impact, how it recruits and is smuggling foreign fighters. nick you had a remarkable conversation with an isil fighter who left the group and is now a refugee in turkey, right? >> reporter: yeah, john, good evening. we rarely get a look inside of isil. how the group is organized. why its fighters might join and why those fighters might become disaffected. and how the religious and military message might attract so many people. and two men who got out. >> reporter: each time this man walks into this turkish mosque, he closes the door on his troubled past. he is the mosque's night guard. his boss is the man he calls his savor. if not for this man, he would have been a suicide bomber in the islamic state of iraq and levant. >> i thought they had the highest understanding of religion. >> reporter: just eight months ago, he became one of nearly 30,000 young men in an isil training camp like this one. the isil video may be propaganda, but he says it is accurate. he learned how to fire an assault rifle, how to fight as part of a group. how to fight hand-to-hand. when you joined what did you think they offered you? >> translator: i didn't join them because i thought they were going to offer me anything or i wanted something from them. i joined them because they provided the best religious path. >> reporter: he says isil made him feel like a holy soldier. it was organized like a traditional military. he was lead by an officer he called prince. the day he realized he needed to leave isil was the day he killed a man. >> translator: i was forced to kill. what could i do. i regret it. i was brainwashed. >> reporter: across town this man told me he joined for religious reasons and military might. he was a soldier in the free syrian army. and isil offered more. >> translator: as an fsa fighter, i would come to a base, and there would be no food or money. isil provided all of these things as well as protection. >> reporter: but he slowly realized his commanders were former leaders in saddam hussein's army. he found his leaders corrupt and brutal. >> translator: we saw the isil command were criminals. criminals who only take advantage of the minds of muslim men for implementing their own goals. >> reporter: this man urged him to flee by offering him a job in a different kind of religious inspiration. the shake used to fight with guns, but today he fights with ideas. he travels to syrian refugee camps to debate isil missionaries to argue their idea of command is brutal. >> translator: what is better to wait on the battlefield to kill a woman, or to create a man who can bring a whole nation to life with his thinking. >> reporter: today he totally rejects isil, but still knows the group is incredibly strong, so he is applying for an asylum in europe. so much has been made of isil's external propaganda, but they said the propaganda extends internally as well. not only did one defector say that anybody who objected to fighting against a moderate free syrian army member, that they were traitors. the group said internally every lower level fighter that the two men were beheaded because they were spies. it's just an example of how tightly the information is controlled by the top of the group and only seeps down to the bottom exactly how the top wants it to be. >> nick, i know tomorrow you'll be talking to refugees who are still coming across the border into turkey. talk about the humanitarian situation. >> yes, john, i think it's really important that we talk about despite all of our focus on the strategy against isil, this is a still a humanitarian story, the largest refugee crisis since world war ii. 9 million syrians not living in their homes. that's a third of the country. thousands arriving every day into turkey, and they simply do not have the food, the water, the shelter that they need. >> nick schifrin reporting from istanbul. nick, thank you.

the new president took place. the u.s. is anticipating the eminent signature of a bilateral security agreement that will allow it to change the way that it engages with afghan security forces, and

trying to restore internal security in his country. >> that's rosiland jordan. at the u.n. israel's prime minister praised president obama in taking a fight against isil. >> reporter: a hard-hitting speech from the israeli prime minister, speaking in the second week of the general assembly. during his speech, he attacked president abbas, and the iran regime, but his main point was the threat of militant islam. >> leading states increasingly recognize that together we and they face many of the same dangers, and principally this means a nuclear-armed iran, and militant islamist movements gaining ground in the sunni world. our challenge is to transform these common interests, to create a productive partnership, one that would build a more secure, peaceful and prosperous middle east. >> reporter: earlier isil was mentioned by the syrian deputy prime minister and foreign minister when he spoke to the general assembly. in his speech, he didn't make much mention of those u.s. air strikes that have been taking place for over a week now on syrian soil, but he did say this: >> translator: we stand with any international effort aimed at fighting and combatting terrorism, and this must be done with attention to citizens. >> reporter: as the general assembly draws to a close, the focus was very much on isil. a security council meeting with heads of state around the table,

he would give us a call. he said we would use a tunnel to egypt, and then go by car to alexandria. >> reporter: he said the tunnel was more than a kilometer long. the earth around them suddenly shook and they were forced to turn back. >> translator: we heard a massive explosion in another tunnel close by. we were terrified. it was only then we realized the dangers we were facing. >> reporter: al jazeera filmed this tunnel before the war. the israeli military has since bombed many of the tunnels. people tell us here, there are many tunnels still under these farms and villages. behind me is the border crossing with egypt, and it was somewhere close to here that mohammed risked his life. the only way to palestinians to go to egypt legally is with a permit for medical treatment, duel citizenship, or a work visa for another country. >> translator: we notice the number of people disappearing has increased through the end of the war. the smuggler's work is individual. they are very difficult to catch. >> reporter: mohammed says he will never give up his dream of leaving gaza. >> translator: i will keep trying until i die. i'm sure of that. >> reporter: determined words for a

looking into the actions of six guards who were working at a refugee center to see if they did indeed humiliate people applying for an asylum. the story came to light when a journalist handed over cell phone video to police. it showed security employees humiliating some of the applicants, in one instance making an algearian man who was handcuffed to lie down on a bed that continued vomit. given the political significance these images might have, two other investigations have been opened since this first came to light in other refugee centers. they suspect far right motives perhaps pushed the guards into this action. angela merkel's spokesman said that if the allegations were prove tone be true, they would be repulsive. all of this comes in an overall context, when the number of applicants is skyrocketing upwards. last year it increases to 124,000 coming to germany, this year we expect some 200,000. >> let's head to washington, d.c. now. joie chen telling us what is coming up on

it could be just the first. >> do you feel like your city dodged a bullet that day? >> maybe we dodged a bomb. we got hit by the bullet. yeah, i think we were very fortunate that the cars went the way

along this line. it is going to be a very bumpy night. we're going to be seeing a lot of problems in terms of severe weather as well as tornado watches in parts of nebraska across to kansas and oklahoma, all the way down. tomorrow we're going to be seeing the same thing, just a little bit more towards the east. the problem is, this system is moving very slowly as it makes its way over, so

constitutional court which has suspended the decree for now. >> translator: we did always say the vote was not going to happen, because it is totally against the constitution. we have been reiterating the argument every single time the issue is raised. >> reporter: this sets madrid on a collision course for the cattlelands, who say they will vote regardless. they don't come much more patriotic than this. >> translator: for me there are two issues. one is the economic exploitation. spain is a rich country, but we are becoming poorer. then there is the cultural question. we are catlons, and we can be a part of any state, but the state has to respect our way of life. >> reporter: brand new in a barcelona square is a clock counting down to vote day. many here look forward to the day when the vast

project makes use of an elaborate system of tunnels. sub atomic particles are smashed into each other, the result, occasional and fleeting glimpses of the building blocks of our physical world. when it was founded 60 years ago, the nature was in large part a mystery. but today we know the metal we use in the universe is all made up of a relatively small number of particles and they are subject to observable and distinct forces. but creating collisions would be of little use without the ability to record the energy generated. this has changed both science and the lives of billions of people. >> the internet has been one of the main tools to allow international scientific collaboration across all of the borders, and today we are really heavily involved in sharing the scientific data and sharing computing resources.
