Grounds nt control brow are in an area under government control, but activists say it was the government to fired. This is the signal of the government. The government denies this. It says that the explosions were carried out by terrorists. It has been almost two years of fighting in syria. Aleppo has been the scene of intense conflicts between the government and rebels. Neither have been able to force the other to retreat for good. No corner of the city is safe. James reynolds, bbc news, is double. Istanbul. Lance armstrong has already been stripped of his titles and reputation. He is sitting down to chat with oprah winfrey. She is not revealing what he said about allegations that he routinely used performance enhancing drugs, but she did say that he did not come clean and perhaps the way she expected. Lance armstrong sitting down with oprah for the biggest interview of her career and possibly the most difficult of his. The what he said about taking drugs remains unclear, despite widespread reports that he confessed to doping. I would say that he did not come clean in a manner that i expected. It was surprising to me. For myself, my team, all of us in the room, we were mesmerized. And when pressed on whether he appeared contrite, oprah urged viewers to make up their own minds. I choose not to characterize. I would rather people make their own decisions about whether he was contrite or not. I felt that he was awful. I thought that he was serious. I i felt that he was thoughtful. I thought that he was serious. He certainly had prepared himself for this moment. Lance armstrong has consistently and aggressively denied cheating, even under oath. A cannot be any clearer than i have never taken drugs. A report from the u. S. Anti doping agency led to him being stripped of his seven titles. He issued a statement saying enough is enough. This is a of as much about money as it is about reputation. Jane obrien, bbc news, washington. For more on armstrongs interview and the fallout, i spoke with a columnist for usa today. You wrote today that Lance Armstrong is not sorry he doped. He is sorry he got caught. Pretty harsh. Yes, but i think he deserves it. There is no greater fraud or bigger cheater in the history of sports, in my humble opinion. This ruse, this parade of going on oh road to apologize after more sure raid charade of going on oprah seems a desperate attempt to get back into the graces of the public. We do not know what he said to her yet. He has been banned for life. Do you think anything could get that lifted . Know, there is nothing he could have told her, unless he started to bring documents, checks, all of his calendars, and literally started naming of the characters in his world on this path to doping. But he can do to help himself is have a seat on the u. S. Antidoping agency couch, so to speak, which he has refused to do. If he were to give every detail, hours of testimony, new information, and new names, he could potentially reduce his lifetime ban to an eightyear ban. That would take him to his 50th birthday. By which time these three old for competitive cycling anyway. Exactly. He is pretty old for competitive cycling anyway. You have been very critical of him. He did the doping, but a lot of people colluded with him. He is part of a much wider scandal in cycling. And that is what the u. S. Antidoping agency and the World Antidoping Agency would like to get at. They would like him to confess and to bring in the other names they do not yet have. I think it could be valuable, a terrific story, just to find out the death, to find out how he cheated. Depth, to find out how he cheated. It is a valid story to have. It is an important conversation about what his role is. But the reality is, at this point, you definitely have to look at him and wonder if you can trust anything he has done. Thank you so much for coming in. French president Francois Hollande says military intervention in mali will only end when the country is safe from terrorists. The country is attempting to drive out rebels linked to allocate a. Linked to alqaeda. No boots on the ground from britain, but a small supporting role in what is shaping up to be a major african war. Planes arrived this morning carrying french hardware and a handful of french troops.

We have seen, he says, that the enemy is ready to fight and should not be underestimated. In malis capital, the french are already being seen as saviors.

Still to come, months after we takeoting in newtown, 0 a look at one lawmaker who has taken the lead in trying to prevent future violence. A military train carrying new conscripts crashed in the early hours of tuesday in egypt, leaving 19 people dead and more than 100 injured. Our correspondent has visited the accident site and sent this report. The train had been used to transport Army Conscripts from all over southern egypt. It was traveling at high speed when the last two carriages decoupled. One smashed into a freight train. The other flew off the tracks. This is just one of the carriages. The train was packed with new recruits. It is now lying in pieces. The dead and wounded are scattered all over this area. Over 100 were injured. I saw a friend holding onto the door handles, but he slipped down and the carriage was entirely destroyed. I dont know if he is alive or dead. Egypt has a notoriously bad real safety record. Just two months ago, around 50 children were killed when a train smashed into a school bus. After todays accident, the officials from the government blamed the mubarak regime and the corruption that left for rail infrastructure. Emergency services were slow to respond. What happened is negligence. There were no ambulances or anything in all. We went to the police station, but they told us they could not do anything. Egypt says politicians need to set aside their wrangling and prevent another disaster. [inaudible] [no audio] as we were driving over, i happened to pick up on social media, not just one person shot, but 20 people dead. After a while, the kids were all leaving with their parents. He just started wandering around thinking, where is mine . Then, confirmation of the worst. The Police Confirmed that 20 children had been shot. The room erupted. I remember i started shaking and could not stop for the life of me. Everyone is thinking, which kids . It is not mine. There are more than 20 people in this room. It is not mine. They gave a status report and it had to be announced that everybody left in the school was dead. A month on, a few flowers remain but the sign for Sandy Hook School is gone. It is far from clear whether the school will never reopen. A lot of people would rather sandy hook be demolished and turned into a memorial. With the town does agree on is that from tragedy should come transformation. For many here, that means gun control. Tomorrow, the president who shed tears for sandy hook will call for stricter background checks and a renewed ban on assault rifles. Gun sales have soared and the gun lobby has powerful friends in congress. All of the shootings that have come before have been terrible tragedies, but with very small children being the target, how could it possibly get worse . If they cannot address this now, it is as if they think they will never address it. They will give up, and this will go on. Body was found cradled in the arms of a classroom assistant, and agonizing loss and a force for change. Families are still suffering unimaginably. For more on the steps lawmakers are proposing to tackle gun violence, i spoke with democratic congressman bobby scott. Thank you for joining me. When you look at what has happened to gun sales in america since newtown, in your own state of virginia, for example, they have spike. It gives you a sense of what you are up against. It does. The Vice President has received a lot of input from different people around the country. I think he will have some very good recommendations involving gun safety, and assault weapons ban probably, a limit on the number of bullets that can be in a magazine, of background checks and other things for gun safety. He will also hopefully have recommendations for Mental Health. All of the people involved in this shooting have had what should have been obvious untreated Mental Health problems. Health care reform will go a long way in making sure that Mental Health care is available to everybody. And then a general Crime Prevention and peace where you invest in young people to get them on the right track and keep them on the right track. The conn. The new york governor has just signed new laws restricting gun sales. How much to you expect to encounter resistance from the gun lobby . There is a difference between restricting and making sure that only the right people have access to these firearms. That is why background checks can be extremely important. Virginia has gone backwards. We had a limitation on the number of firearms you goodbye to one gun a month. That was the law for almost 20 years could buy two one gun a month. That was the law for 20 years and it was repealed last year. I think background checks for criminal records, making sure Mental Health records are available, have that in the database and deny access to firearms. What about broader restrictions . You will be up against the National Rifle association, no particular friend of yours. They are not going to be happy with any kind of restrictions on gun sales because they are lobbying for the gun industry and their profits. There is a difference between limitations on purchases and limitations on who can purchase. There is beginning to be a consensus that those who are ineligible to by firearms should be restricted. People who have criminal backgrounds are ineligible to buy. There should be a universal record check. Right now, there are so many ways to avoid the record check. You do not have any background check of all. You just go pay your money and get your firearm. Thank you for joining us from capitol hill. Those plans being unveiled tomorrow by the president. You may never have heard of graphemes, but it has the potential to change your life. It is billed as the worlds thinnest and strongest material, and the global race is on to get it, i use it and sell it. A science fair in manchester and excitement about the revolutionary material graph scene. Manchester has pioneered asearch into gradsteiphine, material so thin, it has just a single layer of atoms and many potential uses. You can take it and throwing out the window and it will not . It is strange. It is contained in the tiny black flecks on this tape. It has been called a wonder material because it is destined to be incredibly useful. Lets use Virtual Reality to get a closer look at this stuff, because it has extraordinary properties. If you scratch it, it turns out to be stronger than steel or even diamonds down at the same scale, useful for making all kinds of things more robust. It conducts electricity better than copper, vital for future electronics. You could have a computer screen that you could fold up like paper. No wonder people are talking of graphine as a material that could revolutionize the way we make things. This promotional video from samsung shows one view of the kind of gadgets but could emerge. Paper thin, flexible, three dimensional. There is a huge potential, according to the scientist who started the research. Take any bigname, ibm, samsung, intel, all those companies are very excited about what can be done with this material, what this can be used for. Graphine is seen as so valuable, it is now part of the global contest. There is a race to export it. Britain was first to investigate this strange new substance, but it is not clear who will get the most out of it. Quakes graphine, remember that name and remember that you heard it here first.
