on the ground, and american drone strikes from the air and repeated al qaeda counterattacks. this is an attack on siege. street, we can find little public support for al qaeda, but plenty of anger over the drones. who do you blame for the destruction of your town? >> he and his two children were outside a health clinic when they were hit by an american strike. they ran to the school and hid in the basement, but then, the

school was hit also. carried his children out, and his son survived, but his eight-year-old daughter bled to death. president obama says drone strikes kill far fewer people than conventional operations. there is one of

the most pro-american voices in yemen. >> the drones have been one of the most effective tools. attacking civilians for no reason. apology.or issue an >> last september, one person was working in the fields, and his father, mother, and sister had gone to visit the local health clinic. it was 3:00 p.m. when he heard a buzzing noise in the sky, and he looked up.

given to usage was by a local journalist, and it is too gruesome to show in full. they were coming back from the waset, and the target probably a local al qaeda leader, seen traveling on the same stretch of road. 13 people were incinerated. the yemen government has promised an investigation into the attack, but no one we had spoken to had seen any evidence of an inquiry. claim to that does offer justice and redress is al qaeda. and provide funeral costs also financial support of the

families of those killed, and they also pressure the relatives of those killed to join up to get revenge. it is clear it even when they lose members, al qaeda uses the strikes as an opportunity to recruit many more. , andquested and interview the foreign minister did agree to an interview. everyone in yemen we have spoken says this is a successful recruitment tool for them. argument,heard this and there might be some truth in it, but i think the fact is if your target are al qaeda leaders , and if they are endangering the security, there is no alternative. >> the u.s. provides hundreds of millions of dollars in civilian , but the noise from

targeted strikes is drowning out other progress. opposition in the streets is growing. level, winning in yemen is harder than it looks. bbc news, yemen. a brief time ago, i discussed the situation in yemen and the warning for u.s. citizens to leave with a man who formerly served with the state department counterterrorism unit. it like being inside the state department when a decision of this gravity is taken, to evacuate diplomats by helicopter? >> it is a serious situation and gives no one a pleasure come because diplomats want to be doing their jobs and to be on site and meeting with officials

and civil society, so it is taken as a setback, but everybody realizes in situations like this, you have to take the prudent course and protect human life. >> do you think the shadow of benghazi and the death of ambassador stevens is hanging over this? if you have lost one ambassador, it will look at losing more diplomatic personnel. i do not think there is anything surprising about that, and the other point is that by taking these steps, there may be some deterrent effect, because the terrorists themselves are not going to want to strike empty buildings. >> they have criticized the u.s. and the british, saying it helps the extremists. is that true? well, no one likes to pull out their people or close their doors to a threat.

it is obviously not the image that you want to present to the people of yemen, but at the same time, it would be far, far worse if we were to leave the diplomats there and a successful strike were to be carried out. loss of prestige and status and a deterrent force would be enormous, so there are trade-offs, and this is an unfortunate one. >> speaking of trade-offs, drone strikes can kill militants, but as we saw, they also flare anti- american sentiment. what is the calculation there? >> the u.s. government has done its best, no matter what the action taken to minimize what we call the blowback effect, the consequences of any use of force involved, and it certainly is something that everyone wants to avoid. imminent threats, sometimes you cannot avoid taking action, but i do think we have to he careful about

overstating this. i happen to know the yemen foreign minister, and i agree with him that there may be some truth to these statements, but it has been very much overblown. ,he president of the country and he is a very good barometer of sentiment in his country, he has been a far stronger counterterrorism partner than his predecessor, and i think that it has helped with some u.s.s >> in other news, senators john mccain and lindsey graham have called for the and it wasprisoners, said that there could not be negotiations with members of the muslim brotherhood while they are in jail. beguntrial officially has about the man who is accused of killing 13 people at fort hood, leaving more than 30 wounded back in 2009. he is defending himself in court

, and he will be questioning those he allegedly shot. from texas, we have this report. >> such is the security that theng the case courthouse has been turned into a bunker, with things most commonly seen in baghdad. at fort hoodility itself became a combat set, and there is this review flee unseen footage, showing soldiers fatally wounded before being shipped back to afghanistan. armywere shot by an psychiatrist who was then taken down by police. the self-confessed killer was motivated by what prosecutors called a jihad duty, set out to kill as many soldiers as he killing keep them from the taliban and, and he said he

was on the wrong side and therefore switched sides. they continue to describe these act ofs not at that terrorism but an act of workplace violence. therity precautions, it has heel of a terror trial. sergeant survived and will now be cross examined by the man who tried to kill him. he was shot seven times. >> i will not show fear in the face of the enemy, and he is the enemy. i will not show fear in the face of a man who unsuccessfully tried to kill me seven times. i will look him in the eye without any fear, and i will speak the truth. i will let the sword of justice swing down and justice be done. >> you would like to see him put to death? >> yes, yes.

new proposal from the united states and that if he were to put a new proposal on the table, he would like the united states and its european allies to react to it positively. >> so who is going to make the first move in this chess game? the first chess move now, standing up as the new president, making a declaration in front of the people and the conservative elite, and my expectation is you would match this signal with a signal of your own, and then we can go from there. >> but he also said he wants the u.s. to lift sanctions, and that is not a signal they are going to make, is it? >> we want them to suspend their nuclear program completely, and they want the sanctions to be gone completely, so in some ways, it is good because he is stating a goal. we will come to the negotiations see the sanctions go,

and you are going to come to the table to see the program stop, so at least we are clarifying what we are doing, and that is a good place to start. >> how would you be responding? >> they should still say they are serious and that they are willing to explore both sides to see what they can get out of it, and this might actually be in new york. there will be more signaling happening during the united nations general assembly. >> what should the specific signal being? >> we are in a period between so clearing the air and really signaling that there is a new beginning is very important. specifically, what do you think the u.s. can do? may be

the new president of him ran would be there also. >> i think it is that the united states is willing to discuss reliefgree of sanction given a real iranian change. there is a pass here. there is more room to negotiate with americans. >> it is still the overall charge. >> but they are also skeptical he will deliver at all, so they have given him sufficient enough rope to hang himself. you are perfectly free to signal them. go and negotiate. i do not think you will come back with anything, and we have to help him not to fail. >> take you very much, indeed. you are watching "bbc world news america."pear go -- and the european commission is

tellence, even though the two have absolutely nothing to do with another. the second concern is you may be taking away from the hard work of the athlete. i do not think anybody andgrates the hard work skill of michael jordan, who happens to be taller than 99% of the population. can it be that hours of practice make a better athlete? it will help my tennis? was not a rule but came from a study of 10 violinists who were already highly screened for being talented, so all of humanity mostly screened out already, and then there was still variation among them. chapters, i wrote about two high jumpers, and they averaged 10,000 hours, but the guy who had about zero hours won the world championship over the other guy, so you really want to

how curiosity got to work, exploring the land for clues about if he could ever have supported life. let's imagine we could be on mars right beside curiosity. a most frightening thing is its sheer size, but this allows it to carry more instruments than ever before to see if life could ever have existed here. now, the first discovery was on the surface itself. curiosity was among rocks that had formed the bed of a stream, so we now know that water flowed here in the ancient past, and then the rover extended an arm in a complicated set of maneuvers to try something never attempted before on another planet, to use a drill on the arm to drill below the surface just a couple of inches, some centimeters or so, and the results are amazing. it revealed a kind of clay that

could only be formed in water with the right chemical balance for life. in fact, the water would have been drinkable, proof from nasa of the first discovery of a potential habitat on a world beyond our own. a rock from an old street in britain, very similar to what is being found on mars, and part of the nasa science team says the findings are incredibly important. >> this water would not have been too salty or acidic. on earth, this is perfect for life to thrive in, but on mars, we have rocks perfectly conducive to life in the ancient past. >> curiosity is on the move again. once flowed here, and we now know that life at least had a chance. bbc news. >> and that search for life on mars brings today's program on mars to a close.
