tourists. quite a storm for the leader and an outspoken father. find out why short limit. >> celebrations - some argue that the past should not be araised. -- erased iran's supreme leader questioned the details of a nuclear deal made with world powers. ayatollah khamenei demanded all sanctions by lifted at the same time any deal with the nuclear programme was concluded. that was not agreed in a framework deal during marathon talks in switzerland. world powers want a gradual introduction. it was hoped the deal will be finalised on 30 june in yemen the situation is complicated where iran is accused of backing

houthi fighters. thursday secretary of state john kerry said it was unacceptable. khamenei called for the saudi-led air campaign to end, calling it a criminal act. more on that shortly. erica wood on what khamenei's comments mean for the nuclear deal with iran. >> translation: any final approval of iran's nuclear agreement has to come from this man, the supreme leader ayatollah khamenei. the latest comments show there's some way to go before it's a done deal. >> translation: what has been achieved so far does not guarantee a deal and neither do the talks leading up to the deal. it doesn't guarantee the peace talks will continue to the end and lead to a deal. >> reporter: the hard line talk will be disappointing for the p5+1 involved in the marathon final talks in switzerland last week, there iran agreed to limit

the iranian president was part of the negotiation, he too, is talking tough. >> we will not sign any agreement unless all economic sanctions are lifted at once much on the first day of the implementation of the agreement. >> he has a fine line to walk politically both internationally and at home. so far he's managed to remain popular with conservatives in moderates in iran, and he must convince skeptics of the deal, that his country is not bowing to western pressure. u.s. president obama has to convince his skeptics, mainly in congress. >> and i am convinced that if this framework leads to a final comprehensive deal, will make our country, our allies, and our

world safer. >> reporter: but the deal has critics, including israel. france and saudi arabia are france and saudi arabia are also cautious. a deal between iran and the west is always going to be about more than just the nuclear issue. it marks a change in relation tos after decades of political hostility. no doubt the next few months will bring more hard bargaining and tough rhetoric before the final deadline on june 30th iran's supreme leader spoke out about yemen, accusing the saudi-led of committing crimes. the u.s. blames iran making it worse. it made the war of words,le humanitarian conditions on the ground is worse. this report on a battle to get

aid. hashem ahelbarra has this report. >> reporter: these are from the international committee of red cross arriving in the southern yemeni city of aden. the doctors arrived by boat after the trip was approved by the saudi-led coalition. >> it's a mandate of the icfc to make care of the victims of war. for us, as a surgical team, we have the skills and expertise to treat the special type of trauma caused by high-speed bullets and bombs. >> reporter: the united nations chief is concerned about yemen's deteriorating security and humanitarian situation. >> ordinarily yemeni families are drugging for the basics - water, food fuel and medicines. hundreds of civilians have been killed. hospitals and schools are shutting down some of which are direct targets of the fighting. >> reporter: /* >> reporter: the conflict in yemen made life difficult for millions of people.

no clean water, electricity is cut most of the time and people have to queue for days to fill the cars. the cars. we have been waitting for four days in this queue for gas. today is the fifth day. we are hopeful. due to the air strike, the gas tanks were not able to arrive. we are waiting. we borrowed money for gas, that's because those targetting yemen and the yemeni people. >> reporter: there's discontent across the country. dozens of angry soldiers besieged the central bank of the tiaz saying they have not received salaries since september when the houthis took over the capital sanaa. in aden civilians take cover in the city center, where fighting continues between houthis backed by soldiers loyal to the president saleh, and forces loyal to president abd-rabbu mansour hadi. in the port city of makhar hundreds flee.

they have been stranded waiting for the first boat to sail away. those that are lucky board the small boats, headed for eastern africa, leaving behind a country on the verge of a civil war. let's get more from hashem ahelbarra in doha. you talked about the humanitarian situation. bring us up to date with the military developments on the ground. >> basically the saudi-led coalition is continuing its attacks, targetting houthis, and forces loyal to former president ali abdullah saleh. they say they are undermining their capabilities. what we have seen on the ground at the same time is the houthis, despite the attacks managing to control areas in - morale in the south, predominantly sunni area much this comes as a significant setback for the saudi-led coalition, because the aim was basically to push the houthis

back. we are seeing in the country the houthis moving further in the southern part of the country escalating tensions it seems, every day between saudi arabia and iran. >> well saudi arabia present itself as a defender of sunni islam. iranians present themselves as the champions of the shia cause. the two are the most powerful countries in the regions, there are concerns that yemen could become a battle ground for iran saudi arabia confrontation like we have seen in the past in places like syria, iraq. the saudis say that iranians are providing the houthis with military aid to destabilize the region. the iranians on the other hand are saying that the air strikes have to come to an abrupt end

and diplomacy should prevail. it's a delicate situation. >> thank you for that update. >> well the u.n. secretary-general says the residents of the yarmouk refugee camp on the outskirts of damascus are in the deepest circles of hell. 18,000 are inside the camp after fighters from islamic state of iraq and levant overran it last week. aid agencies called for a halt to the fighting so aid can reach residents facing food and water shortages. russia's foreign minister thomas love -- sergey lavrov to put an end to the fighting. they are hosting talks to the government and some opposition figures. the main group is boycotting the meeting. rory challands has more.

>> for the first two days of 4-day talks the opposition groups discussed things among themselves. the government's representative turned up on wednesday when he did, he was handed a document formulates by the opposition and it includes discussions of humanitarian issues and fights against terrorism. it doesn't discuss the fate of bashar al-assad, syria's leader. that is important. remember, the syrian national coalition, the main opposition group in syria has been boycotting the talks, seeing the removal of bashar al-assad as a main precondition for any kind of negotiations. but the landscape for syria's oppositon groups shifted since the war began nearly five years ago. recently we have seen the rise of islamic state, and this replaced bashar al-assad as the main bogey man in the region for the western government. we have detected a noticeable softening in the language that

the united states uses when it talks about bashar al-assad. the other thing that happened, of course, is the nuclear deal with iran, when sanctions are lifted against iran, this will allow iran to operate more freely as a regional power, supporting its allies, one is bashar al-assad. what is good for bashar al-assad is, of course, bad for syria's opposition. three attacks in egypt's north sinai region killed 13 civilians and four soldiers. a missile landed on a house in another village, a third attack was a military vehicle. the government has been fighting a group that pledged allegiance to i.s.i.l. ahead - a french television network is taken off the air after a cyber attacks. a group claiming links to i.s.i.l. is to blame. >> i'm paul brennan in the green fields of england, where the

sound of farm machinery could be overtaken by the sound of heavy oil drilling equipment.

a reminder of the top stories. iran's supreme leader ayatollah khamenei says the nuclear accord with world powers is not a guarantee of a final deal saying all sanctions must be lifted once the deal is agreed. khamenei has been speaking out against the saudi-led air strikes strikes in yemen, calling them a crime, and called

for a halt in the fighting and peace talks to begin. >> the u.n. general described the situation in the refugee camp in damascus as a circle of hell. children have been used as human shields after i.s.i.l. overran it last week. greece made a repayment of $500 million to the international monetary fund. that means it owes $24.5 billion to the i.m.f. greece must repay under 350 billion. the largest aim, 141 billion is owed to the european financial stability, set up to help with the final crisis. barnaby phillips follows developments from athens. >> reporter: greece will owe bunny it the imf if weeks to

come. it's living a hand to mouth existence. scraping together money to pay pensions and salaries to civil servants. it needs a lasting agreement with other european partners. that looks difficult because of the suspicion that has grown up over the previous weeks between the administration and other governments. we saw irritation across europe over alexis tsipras going to moscow, and saying there that greece did not support the e.u. sanctions against russia over its alleged military involvement in the ukraine. i don't think it went down at all. there has been a disagreement between greece and germany with greece saying that germany owed it money for reparations in return for the nazi operation dating back to the 1940s. all is making it difficult for the greek government and the

european union to finalise an agreement the french television network is trying to restore its service after a cyber attack. a group calling itself cyber caliphate is thought to be behind the hacking. >> reporter: in television a black screen spells disaster. when several french channels went to black on wednesday night producers in this office knew something was wrong. the channels' director says he was shaken, and the problem is not over. >> it's been a very powerful cyber attack. we have very strong fire walls and that had been checked very recently. they were said to be very safe. >> reporter: this is how seriously the french government is taking the attack. not one, but three ministers spent the morning at tv headquarters, armed police underlying the sense of urgency.

>> translation: we have taken measures in order to respond at a technological level, because it's necessary not only to deal with the situation, but to get ahead of what the terrorists in their sick brain might have in mind. >> 11 tv channels were taken off air for a brief period. messages like imif, a reference for islamic state of iraq and levant kept popping up on the network's website and social media. on facebook a message read: the so-called cyber caliphate staged a similar online ambush before. at the start of the year it hacked into a twitter feed run by the pentagon. the message to american soldiers said "watch your back." in the newsroom a reminder of an attack on the paris based satirical magazine "charlie hebdo".

since then french media has been an alert. france is part of the coalition fighting i.s.i.l. in iraq. this is a different kind of warfare. and very sophisticated. to of france's controversial poll tins had a public falling out. marine le pen, leader of the national front is blocking her father the former boss running for a ke political roll. >> reporter: she was his vocal supporter, or was. he was straight to be president at one point. his daughter marine le pen by his side. now she is leader. john le pen outspoken remarks too much for her. marine le pen will block him from running as leader of one of france's regions, and she wants to distance herself from him.

>> they do not share the same ideology, and they do not belong the same generation, and there's an internal fight within the as to whether the founder, john le pen should remain or not. >> it's a fight that many have seen coming. john's outbursts are more and more uncomfortable... scribing the nazi gas chambers as a detail of history, praising a war time leader that collaborated with the nazis, and question loyalty to france. the daughter's response:

leading to a move from her to call a meeting with the party's executive bruro to: -- bureau to fined best way to protect the interests of the movement. for marine le pen the goal has been to convince vote theirs her party is the embody. of what it means to be french. take joan of arc, they adopted her as a symbol. the feeling is that that kind of history helps, it's the more recent history that is a hindrance. notably john le pen's musings on various subjects which is why his opinions are not required or wanted when it comes to his own daughter. national front may be united front - not for that family not at the moment a man on trial for bankruptcy has shot dead a judge, a lawyer and a co-defender at a court in iran. he shot the judge his office and

the lawyer and co-deft in the courtroom. police arrested him after the incident in a town north-west of the city oil prospectors found indications of a multi billion oil field in the crean hills of southern england. estimates predicted moderate amounts for the wheel basin. now an investment company claims there could be $100 billion barrels in the area. >> reporter: the rolling countryside of englands southern counties is as far away as you can get from the typical image of an oil field. analysis of test trilling has parked talk of a bonanza, black goals among the fields. it's operated by u.k. gas and field industries. >> it's like a huge response 1,500 feet thick with vast amounts of oil and limestone that you could suck out the oil

with a sponge. there's a lot of work to be done but this will be a part of britain's strategic energy resource. >> it's important to look at what the company is saying in the statement, and it's peppered with caveats, talking about drilling work producing estimates, saying there needs to be ongoing analysis and possible world class, potential resources. what is clear is that nobody really knows how much oil is here. that didn't stop the share price rocketing on thursday up more than 400% at one point. just a year ago independent scientists from the british geological survey estimated there was 4.4 billion barrels and there is skepticism about whether predictions of $100 billion are realistic and achievable. >> analysis showed something in between, 40 billion barrels.

it's significant, but only when you show and demonstrate that the oil on the ground 1,000, 2,000 meters below get to the sufferers. >> reporter: environment groups and local residents are horrified at a frenzy of prospecting. >> horses need to be quiet at night. this will go on 24 hours a day. we had a lot of disruption. >> reporter: the confusion over data is understandable. if accurate it is a recent discovery. talk of a bonanza of black gold until then is speculation. president obama is preparing to fly to panama where he'll join other regional leaders for the summit of the americas.

all eyes will be on a meeting with raul castro. before it started there has been clashes. >> reporter: shouting matches. a warm up for the much anticipated handshake between u.s. president president barack obama and cloouban leader raul cast i don't they had pulled out from a social forum after dissidents described as mercenaries were allowed to attend. >> this is a farce where they thing enemies will talk.

>> reporter: two opponents had been invited. >> in the next few days leaders of the americas will be able to show courage, to support and hold free and multi party elections in cuba. >> reporter: for the first time since it was expelled from the family of americas 53 years ago commoounist cuba has been invited to sit at the same table as the united states an invitation issued by panama's host and president. >> there are two places and all countries share a commonplace. that is panama. a country uniting people. >> reporter: this was more than a personnel decision. inviting cuba was a regional alt mitt um by president obama,

issued by latin american peers. >> this is a first step by the obama administration to show vary willingness to have a cordial relation with latin america. president obama hoped to announce the establishment of full diplomatic relations with cuba ahead of the summit. allowing cuba into the fold is a guest oar of enlightened self-interest, helping washington recover lost clout at a time when china is making unprecedented inroad in what was considered the backyard of the united states. the ideological divide between cuba and the united states is enormous, a gathering of all the neighbours of the americas for the first time represents more than a photo opportunity south africa's cape town university bowed to opportunity pressure and removed a statue of

a british colonialist. many say the mon oument was a symbol of white soup rem sis. sue turton reports. >> reporter: an unser mope call end to cecil rhodes, as his statue was removed from the university for safe keeping after weeks of protest led to a vote for its removal. most of the students were born after the fall of apartheid. to them this british colonialist represents a university system failing to decolonize or embrace african knowledge. >> is the university trying to protect itself or funding or is it not interested in integrating into the greater area of deolonizing, it's a conversation about decolonization. >> reporter: similar protests

targeted the president kruger's statue and the war memorial in pretoria, with a counter aring exchanges at the av carnes museum. other effigies of british going george v and the prime minister lowy bova have been defaced. in the vaults of the heritage foundation in pretoria row after row of art works from afrikanns history. busts and paintings removed, that the curator is committed to protecting as she believes they hold historical significance. we have to cherish the diversity of the culture. it will take a while. i hope they are not thinking by demolishing or scrapping evidence of the past that erases the past. you can't. we are all the products of centuries of predecessors, and what they did and accomplished. >> reporter: the final destination for cecil rhodes statue is up to the south african government.

the zimbabwean president on a state visit said he had decided against removing cecil rhodes remains from his grave in case the spirit rises more stories any time on the website. the address is aljazeera.com. you can catch up by clicking on the "watch live" i con. i con. hi, i am lisa flesher and you are in the stream. nonprofit hospitals are supposed to take care of people regardless of their ability to pay. why then are some suing patients for millions. and the is i.r.s. doing enough to stop it? could this be the beginning of the end for the cable television industry, a new internet t.v. services are capturing consumers. and a new battlefield in the information age why some around the globe are an
