And the impossible climb made possible. Two free climbers scale the sheer rock face of el captainitan in oweYosemite National park. Hello. Thanks for joining us. This is an infrared satellite image of the nigerian town of baga. Its been released by Amnesty International to show the scale of destruction after an attack by boko haram militants last week. Well amnesty says that 620 buildings in the town were damaged, a lot of them completely destroyed. I want to give you a clearer picture as to whats happened here. This is the image from the second of january, so ahead of the attacks. Overall, lots of vegetation. You can probably see the buildings in between there. If we now mix through to the scene after the attack the buildings have all gone. Not much vegetation left either. But essentially razed to the ground. The officials in the northeastern border states say that attack killed 150 people. Other reports, though put the death toll as high as 2,000. Its just one attack among a whole capital. Heavy fighting broke out on friday, as the Nigerian Military managed to hold off boko haram fighters. But those fighters then tried to take another town damaturi. On saturday a bomb strapped to a girl killed to be just 10 years old killed 19 people. A busy market was targeted on sunday. Two young women blowing themselves up on this occasion killing at least four people injuring more than 40 others. And then on monday authorities in neighboring cameroon said they managed to repel an attack by boko haram insurgents on one of their northern bases. And on wednesday, nigerian authorities said they had pushed back a militant attack on the town of bu although two antiaircraft guns were stolen in the process. The bbcs will ross has the latest from les gos. Reporter these images show the devastating impact of a major boko haram attack. The first Satellite Photos were taken the day before the jihadists struck. Then four days later, burntout buildings can be seen in baga town. Amnesty says 620 buildings were damaged or completely destroyed by fire. In the nearby settlement of doran baga more than 3,000 structures were targeted. The gunman captured the military base before shooting whoever they could in baga and the surrounding villages. Much of the northeast of nigeria is extremely inaccessible and dangerous. So much so that these first pictures of the violence around baga have come from these satellite images. They show the destructive nature of the group, boko haram, but they dont give us anymore clues as to how many people were killed in this violence. The Extremist Group has a long track record of violence against civilians. The Nigerian Government says no more than 150 people were killed in baga but people fleeing suggest the number is far higher. One eyewitness tells the bbc that the jihadists have detained hundreds of women in the captured town. They wouldnt be the first to be held against their will by boko haram. More than 200 schoolgirls kidnapped nine months ago are still not free. The Nigerian Military has managed some successes, repelling recent boko haram attacks. But the jihadists seem to be growing in strength. On a visit to nigeria, the former head of the United Nations spoke to the bbc about the crisis in the northeast. They are brutality, the murdering of innocent women, children, and men cannot be condoned. They are determined to instill fear and intimidate the population in the whole area. And not just the government. With the support of International Partners should do whatever it can to end the insurgency. Half a Million People have now fled the violence and headed for the main city. There they can get some help but the humanitarian agencies cannot get to the worsthit areas. This conflict is destroying communities and tearing helpless families apart. The baga attack marks an escalation in the crisis. Will ross bbc news legos. Speaked to suleman about whether these new pictures were getting give any clearer indication of how many people were killed in the attack. In terms of the number of people who were killed the pictures do not show or verify the numbers that we are getting. But i think from the pictures the extent of destruction is huge. This is a town baga which from the pictures you can see that if you compare the two pictures the one before the attack the one after the attack you can see a number of buildings that were razed to the ground. The destruction is really huge. But indeed it does not tell us about the number of people that were killed in the attack. No. In terms of the way i mean there are buildings that are gob. Theres absolutely nothing left. All just burned to the ground. Indeed, they were burned to the ground. And we get these accounts from eyewitnesss who live in the town of baga who say many buildings were razed to the ground and they are the same people who said a number of people were killed. And a local Government Official from that area put the figure at 2,000. But the Government Officials are saying, 150. And you have to question them. Because this is a town that was taken over by boko haram. How they were able to verify that only 150 people . So the best i think, figure you can take is from the people who were in the town who suffered that attack and who were able to flee. Because they told us after they were fleeing, that boko haram was following them and shooting at them and at other people. But the government says that only 150 people were killed. Yeah i suppose that was the point they were making that many of them had fled before boko haram got in. And another question to ask, boko haram went into the town. If the town was empty, why then burn the town down . They would just take it over if the town was empty. So presumably there were people in there, and that was why, in order to instill terror into them is to burn down the town and then kill them and that is what boko haram has been doing for quite a long time. There are elections in its a month precisely, now, isnt it . A months time. Can we gauge how much damage this is doing to the government or not, indeed in terms of those elections . Well the thing is i think the government and the opposition parties are continuing with their campaigns. I mean, some of them make reference to the violence that has taken place and some of them might not even make a reference to what is happening. The big question is that how is the government going to conduct election in these areas . Because these are areas that are no good areas for the military service. How do they expect Election Officials i mean election to go there and expect people to go and work . But still, people are insisting that elections are going to take place in this area. Now one has to wait and see what is going to happen if there is going to be a miracle. Because nigeria is going in there, how in one months time its going to bring peace in the area, for people to be able to work. The french president , Francois Hollande, has been speaking about the role of islam in france. He was giving an address to the Arab World Institute in paris in the wake of course of the killing of 17 people by terrorist militants in the country last week. He said muslims were the first victims of fundamentalism around the world. Islamism of all convictions and influences. All the miseries and inequalities. It stems from all the conflicts that have not been sorted for a long time. And it is the muslims who are the first fixings of fundamentalism and intolerance. We should also remind people and i do it every time whenever i happen to be in the arab world, that islam is compatible with democracy. Francois hollande there. Well in berlin new security measures have been announced by the german chancellor, angela merkel. This is partly in response to the attacks in paris. The president began todays parliamentary session by leading a one minute of silence for the victims of the paris attack. Chancellor merkel then gave measures, among them tightening an existing travel foreign ban for known islamists to stop them heading to war zones like syria or iraq. Lets catch up with business news. Aaron has the details of showme. I should get used to saying that. Very good. Somehow showme. Chinas showme has staked its claim to apples crown. We are talking about the worlds third Biggest Smartphone maker and the most valuable tech startup unveiled its flag ship my note. And its a challenger. A challenger to apples iphone 6 plus. Why is a chinese launch from a chinese phone gaining so much International Attention . Xiaomi is one of the first big chinese brand thats starting to make its presence known around the world. There are even rumors it might announce an american launch on thursday. Just three years after xiaomi sold its first smartphone a 1 billion round of fundraising, which was announced in december valued this chinese tech giant, the value to have the company at 45 billion. Were going to have more on gmt coming up on that one. Were also going to be looking at scotland, where the north Sea Oil Industry has been battled by those plunging oil prices. Bosses at bp are talking to staff at their headquarters in abidine after a Strategic Review of their north Sea Operations and they are expected to announce what could be the first in a wave of pretty big job cuts. Around 450,000 people work in the uk oil industry. Around half of them in scotland. Under the north sea, it is expensive, very expensive to bring up out of the ground to extract anything under 60 bucks a barrel and the industry warns, its just not profitable to do. We know what brent crude is at the moment. Its trading around 48. 50 a barrel. And we keep reiterating this its down. The value of a barrel of oil has fallen by just over 60 in the past seven months leading one senior industry figure to warn last month that britains oil industry, ouch is close to collapse. Again, were going to keep our eyes on this one. And staying with the impact of oil prices that is apparently why Indias Central Bank made a very big surprise. A surprise move to cut its Interest Rate to 7. 75 , all thanks to lower than expected inflation. This move came ahead of the banks regular meeting next month. And the experts say it certainly paves the way for further Interest Rate cuts. Again, well have more throughout the rest of the day on that. So lots going on. Follow me on twitter. You can tweet me and ill tweet you right back. You can get me bbcaaron. More on gmt in just over an hours time. The fbi has charged a man in ohio with plotting to attack the political heart of the united states, the Capitol Building in washington, d. C. Christopher cornell was detained after allegedly trying to buy firearms and 600 rounds of ammunition on wednesday. Hes also said to have posted messages on social media supporting violent jihad as natalie grimly reports from washington. Reporter this is the moment that the fbi sweeped in on a man that they believe was planning an attack with guns and explosives on capitol hill. Christopher cornell, aged 20 had gone to buy two semiautomatic weapons and 600 rounds of ammunition. In terms of our cooperation with law enforcement, thats something that we do every day. Its a part of who we are, as a responsible firearms dealer. So that was not out of the ordinary. The fact that it was something of this scale, we had no idea. Reporter Christopher Cornell had come to the attention of the authorities after an informer had noticed his messages on social media declaring support for the militant group, islamic state. Cornell is supposed to have posted on twitter last year i believe that we should just wage jihad under our own orders and plan attacks and everything. The fbi allege hed also researched making pipe bombed and had looked into traveling to washington, d. C. He also told an undercover agent that members of congress were enemies. Security has inevitably been tightened on capitol hill though the fbi has been stressing there was never any imminent danger to the public during their investigation. Meanwhile, Christopher Cornells father admits his son may have posted the medicals about violent jihad out of anger, but he says his son was just a mamas boy and wouldnt have been able to carry out any actual attack.

Youre watching bbc world news. Im david eades. Our main news Amnesty International has released satellite images of the nigerian town of baga showing the scale of destruction after last weeks attack by boko haram. Pope francis asian tour is well underway now. Hes been in sri lanka already. Hes now arrived in the philippines to really quite a welcome, as well. And his trip to the country will last five days. Here he is stepping off the plane. A number of the people coming out to see him and to celebrate the performances hes giving. Hes set to visit in the course of these five days a town where hell meet survivors of the typhoon that hit the area back in 2013. A Large Population of catholics in the philippines, of course. Some 80 million in all. I think we can speak now to our correspondent, Rupert Winfield hayes, whos in manilla. Having witnessed already the welcome for the pope its going to be a busy few days. Judging by what weve seen here this evening, its going to be a very few busy days for the pope. The pope went right past me a few minutes ago in his popemobile and the crowds were ecstatic. And there was a huge smile on the popes face as he waved from his popemobile to the crowd, watching enormous crowds here. I mean lining the streets, all the way from the airport, all the way to the middle of manilla. 20 deep on either side of the road. How many people turned out to watch the pope coming to town im not sure but it is probably in the hundreds of thousands. Thats just from the drive in from the airport. So that gives you an idea of what sort of crowds will be turning out to see him in the next few days. Weve got a line running on the screen rupert saying high security for the visit from the pope. What is probably par for the course anyway. But this has not always been a terribly welcoming place for popes. Reporter well its a mixture, because the vast majority of filipinos are both catholic and devout catholic and absolutely welcome the pope and are delighted to see the pope. There are a small minority of people here who are not welcoming of the pope. In particular there are some Extremist Groups in the philippines. One in particular called abu sayet, a muslim Extremist Group in the south of the country, who has sworn allegiance to islamic state, so it is a potential threat. There have been plots against popes on previous visits here. A former plot that was foiled against Pope John Paul ii in the mid1990s. So of course because of that, security is of the highest importance here. With these massive crowds its going to be very very difficult. Having said that i found it very, very easy to walk right through the crowd, through the police line and on to the front row as the pope went past me this evening with just my media pass on. So im not quite sure exactly how tight security is. Remind you, you are Rupert Wingfieldhayes. Rupert, thank you very much, indeed. Now, five men from yemen have been released from the u. S. Detention center at Guantanamo Bay after 12 or more years of captivity. Four have been sent to oman the fifth to estonia. Their release brings down the number of guantanamo detainees to 122. 28 inmates were moved last year you may remember. Well president obamas pledge to close guantanamo when he took office six years ago. The bbcs alina ball has been given special access to the camp. It was meant to be temporary, but Guantanamo Bay is Still Holding prisoners. We got to walk its darkened corridors, and through the oneway mirrors used by the guards, got to see some of the men who have been here for up to 13 years. The vast majority of whom have never been charged with any crime. But some are starting to believe their wait could soon be over. So heres the facility. Reporter because the cells are fast emptying, from a high of well over 700, fewer than 130 detainees remain. Theres been a sudden spate of men released in recent weeks. This is camp five. Its in this block that detainees who are seen as less cooperative are held to punish them and keep them away from other prisoners here and they include the last british resident detainee. He like so many others has spent years being cleared for release, but h
