unacceptable. any final approval has to come from this man. but his comments show there's still some way to go yet before it's a done deal. >> what has been reached so far does not guarantee a deal. neither do talks leading up to the deal. it doesn't even guarantee these talks will continue to an end and lead to a deal. >>reporter: this will no doubt be disappointing to the p5+1 parties involved in the talks in switzerland last week. iran's president was part of

>>reporter: this is how seriously the french government is taking the attack. not one but three ministers spent the morning at the station's headquarters armed police underlined the sense of urgency. >> we have taken measures in order to respond at a technological level because it's necessary not only to deal with the situation but also to get ahead of what the terrorists in their sick brain might have in mind. >>reporter: eleven tv channels were taken off air for a brief period. messages like imif kept popping up on the website and social media pages of the network. one message read the cyber caliphate continues its cyber jihad against the enemies of the islamic state. they have staged a similar online ambush before. at the start of the year it hacked into a twitter feed run

alienate ed. >>reporter: they are too afraid to give information to the government. i met some clan elders who told me why. >> i once gave information to police. they arrested me saying i'm al shabaab. how do they expect us to give them information if we're going to be victimize. >>reporter: somalis from this region accuse police and the military for targeting them in regular government crackdowns. this is the main market. in 2012 three soldiers were killed by unidentified gunmen just outside. there was a government crack down. they believe that the government blamed the traders for it. she was shot in that raid. it took her two months and the help of relatives to rebuild her

hissout spoken remarks are too much for her and she will block him trying to distance herself from him. >> i think deep down he needs to show wisdom and accept the consequences of the turmoil which he himself has created and maybe he should give up his political responsibilities. >> they do not share the same idealology and do not belong to the same generation. many have seen it coming. outbursts have been getting more and more uncomfortable. describing the nazi gas chambers as a detail of history. praising france's wartime leader who collaborated with the nazis.

his daughter response his status as honorary president does not give him the right to hijack the national front with vulgar provocations seemingly designed to damage me but unfortunately hit the whole movement. he intends to express his fuse as a politician who is responsible, free and always walks with his head held up leading to a significant move from her to call a meeting of the party's executive bureau with him present to quote, find the best way of protecting the interests of the movement. the goal has always been to convince voters her party is the very embodiment of what it means to be french. take, for example, joan of arc. the national front has adopted her as one of its symbols. while the feeling might be that kind of history helps, it's the more recent history proving to be a hindrance.

learn education because if we don't have education, we cannot improve our lives or our country. >>reporter: afghanistan has made the fastest progress of any country in the world in the past 15 years and it has one of the biggest increases in enrollment. but the increase has also created problems. afghanistan doesn't have enough qualified teachers or classrooms. some students have to study in shifts. and for those who do graduate going to university is not guaranteed. the exam process has been tainted by allegations of bribery and cheating. the test was canceled in several areas because education officials believed it could not be proper administered. >> we want the government to build more universities and also tackle corruption. >>reporter: afghanistan's education officials say they're aware of the system's

shortcomings and are working to correct the problem. but they say for a country that's endured decades of conflict in education at least, afghanistan is doing well. jennifer glass, al jazeera, kabul indications of a new multibillion dollars oil field has been found in england. there could be as much as $100 billion barrels beneath the earth. >>reporter: the rolling country side is about as far as you can get from the typical image of an oil field. but analysis at this exploration well has sparked excited talk of black gold beneath the fields. >> it's a big sponge. 1,500 feet thick with vast amounts of oil in it.
