others hurled stones at macedonian forces on the other side of the fence. they responded with tear gas. but rumour has spread around the camp that the border had opened. hundreds of refugees ran towards the fence. this woman and her children were sitting around their ten when the rumour reached them >> translation: we ran towards the gate, people shouting, open the borders. i couldn't see further up. they then fired tear gas. i fell while running away. this is wrong. we demand our rights. there is no need for violence. we have to be patient and slowly, slowly everyone will get in >> reporter: but it was in vein. macedonian forces had pushed everyone back and brought the situation under control. >> it was a disaster in the making. people have been stranded here some for as long as ten days.

the camp is over congested and the uncertainty among refugees is overwhelming. emotions are running high. >> reporter: they arrived for a day ago. they walked for hours. >> there is no feeling. >> there is nothing. >> there is no humanitarian here. >> reporter: like many others, she want doers who-- wonders what will happen next. some protesting refugees are still refusing to move back from the fence >> all the people here, they cannot - they said that they will not step back. they won't step back. we want to be here. without food and water. we don't need anything. we just need to open the borders. >> reporter: but most refugees returned to their tents. even more worried now than

europe will tighten its frontiers even further as the debate continues across europe about how to deal with the crisis, more refugees risking their lives to get into europe. the italian coast guard has rescued 51 refugees off turkey. women and children were crammed on a dinghy trying to reach the land. police dismantled the southern half of the camp in calais known as the jungle which has been home to thousands of migrants hoping to reach the u.k. >> reporter: as workmen and the bug dozers work in to try and clear the camp so did those trying to stop them. attempts were made to pull down

the makeshift shelters. activists and some refugees and migrants retaliated targeting the police, throwing stones and setting fire to part of the camp. police used tear gas and water canyon to try to push them back - cannon. >> translation: you can see the protesters didn't hesitate to set fire to tents and shelters or to throw stones at police. it is not acceptable and it's normal that we're going to restore security >> reporter: the camp, or jungle as it has become known, is home to several thousands refugees and my grarngts many ending up in-- migrants, many ending up in calais. the u.k. want to keep them out. men, women and children have found themselves living here in limbo >> there are hundreds of children here unaccompanied. we're worried about them, that

they will go missing >> reporter: the authorities say they are offering people better accommodation nearby or at resefks centers in different parts of france. some have taken up that-- reception centers. some have taken up that offer to move. there is deep distrust here to syria and the ewe nighted nations has stepped up its deliveries of aid to besieged areas. the truce is being tested. this is said to show fighting in the northern province of hamaa. these pictures from the syrian military purportedly show soldiers fighting i.s.i.l. in alham mam. i.s.i.l. is not taking part in the so-called ceasing of hostilities.

the u.s. secretary of state has been speaking about the truce violations. john kerry says it's important they're handle properly >> we have agreed that while there have been some number of violations reported on both sides, and we take them all very seriously, we do not want to litigate these in a public fashion in the press. we want to work to eliminate them. we have agreed on a process by which we will do that. there is a team of people on the ground in geneva and there are a team of people in amman jordan and they are in touch with other and in people in syria. we're going to crackdown each alleged violation and work even more now to put in place a construct which will help us to be able to guarantee that missions are, indeed, missions against al-nusra or missions

against d.a.e.s.h. our correspondent is live for us on the turkish-syrian border. there seems to be a desire for clarity here driven partly by the french as to whether the ceasefire is holding or not. from your vantage point how secure is the cessation of hostilities? >> reporter: it is shaky and fragile. my own count of the number of violations since day one of the truce is somewhere between 65 up to 70. that count is based on information from syrian activists and the syria regime and the regulations. we have reports in the last hour or so on an an strike in the southern countryside. we understand there were clashes between rebels in that area with the syrian army. the activists are telling us that the army was trialling to advance. -- trying to advance. there was also one person killed

in homs. you do have violations. they are ongoing. when you compare them to the level of violence prior to the truce, yes, they have decreased dramatically. i was speaking to u.n. who were welcoming the fact that some aid trucks went to madaya. they emphasizes the that this was not-- emphasised that this was not part of this troop. this was planned prior to the truce. they're still waiting to get approval from the syrian government to reach at least 500,000 people over the next five days a palestinian has been killed during clashes in the west bank. violence started when palestinian gunmen opened fire at a military check point injuring three israeli soldiers. the palestinian ministry of health confirmed the death at the camp. 14 palestinians were wounded in the clashes that followed.

80s. he didn't attend the hearing but that didn't stop 15 victims travel to rome to watch him. >> it seems unbelievable that a man of intelligence was so unaware of what was going on around him. >> reporter: at the time pel was a priest the church war the abuse happened. >> we are now calling on the pope to intervene in this, to intervene in this action that he make and ask the cardinal pell to be more honest about what went on. >> reporter: since sex abuse scandals in the catholic church surfaced in 2001, the vatican has been abused of covering up thousands of case worldwide.

welcome back. the top stories on al jazeera.

police chiefs from greece and several balkan states are meeting to discuss the growing refugee crisis. this comes a day after refugees and police clashed on monday at the greece-macedonia border. thousands are stuck there because of growing border restrictions. the u.s. secretary of state has confirmed that both sides in the syrian conflict have violated a truce agreement made four days ago. however, john kerry says the breechts have not been significant enough to break the suss agency of-- cessation of hostilities deal. the australian cardinal george pell has tested for a third day-- testified for a third day. he denied knowledge of system child abuse. four people have been killed by a suicide car bomb attack in the yemeni city of aden. it was driven into an area where

officers were south africa's main opposition party has gone to court to try to reinstate corruption charges against the president. he has charged with corruption over a 4 billion dollars arms deal 11 years ago. the case collapsed in 2006. it was reinstated in 2007 shortly after zuma was elected president of the car. it was dropped again in 2009. the prosecution says he couldn't get a fair trial because phone tapped conversations revealed political interference in the investigation. our correspondent is following the story. >> reporter: the da will be spending the next three days trying to convince a full bench, three high court judges, that the decision by the national prosecuting authority to drop 783 corruption charges against the president was wrong. this all comes down to what is

known as the spy tapes. these are secretly recorded telephone conversations between the former head of the prosecuting authority and a justice in which there is evidence that they may have colluded on the timing of these charges. at the time of dropping these charges, the national prosecuting authority says that was evident of political interference in the process. the da is arguing that regardless of whether there was political interference or not, the strength, of merit of the case against zuma was strong enough that he should have had enough his day in court. the decision to drop the charges are wanted to be reinstated. he has always argued that there was a political conspiracy against him. he said in a statement last night that this is an effort for the da to sko score political

points. the president will be facing a vote of no confidence so this is a very difficult day for him a south korean opposition party is set to end a national assembly debate which has broken the world record, the longest speech in parliament. it is into its eight straight day. it is being used to block a b l bill. >> reporter: it seems that the chairman of the opposition party has over ruled the arguments of others, including its snud the floor leader of the party who wanted to keep it going longer. worried about a backlash in the public at large as the business of the national has seized up at a time when there is important business to be done. there is an election coming up on april 13. there is an aagreement on

redrawing some of the electoral boundaries that need to go through the national assembly before that that happens. also a recognition that this is an attempt to delay this legislation which is destined for eventually defeat. the reason the opposition has been against this bill is that they say it gives too much power to an organization which they intensely distrust which is the national intelligence service. it gives power, it would give power to the national intelligence service simply to label somebody as suspected of terrorist activities around then they would be allowed to wire tap their phones, gain access to their bank records and the opposition party says that's too much power on too vaguely worded provision. so far as the authorities are concerned, we're in the aftermath of a north korea nuclear test and rocket launch. it bill does seem it will go through. the parties have at least time to make their point as they have

watched these proceedings as never before on the national assembly television and there's so much political coverage has been devoted to this one issue the u.n. security council is set to vote to expand sanctions on north korea later on tuesday. that is in response to north korea's latest nuclear test and rocket launch in january. the tougher sanctions are an attempt to squeeze north korea's income and put a halt to its nuclear program. people have been protesting in pakistan against the hanging of a man convicted of killing a form yr governor. -- former governor. the execution triggered rallies in several cities, including the capital, several religious and political leaders this publicly the killer. they said the former governor deserved to die u.s. presidential hopefuls are preparing for super tuesday. the day when people are voting

for their candidate of choice. donald trump leads the republicans with 81 of the more than 1200 delegates required to win the nomination. his main rivals marco rubio seen here and ted cruz in his home state texas, are working hard to defeat the billionaire businessman. further behind is john kasich and ben carson. about 880 delegates will be awarded on super tuesday in the democratic race which is about a third of those needed for the nomination here. hillary clinton has been campaigning in massachusetts. she is expected to win in most states. her opponent, bernie sanders, has been campaigning heavily in the city of minimum appear loss - minneapolis. nearly every single candidate from both parties has been

campaigning in virginia. our correspondent visited allington to see why winning virginia is so important. >> reporter: this state here, the people who have moved here in the last 15 years are changing the way the state has voted for decades. >> this really became sort of a mid-atlantic tech hubs not unlike silicone valley. a lot of changes that have happened here have been about more educated technology, interested people who are engaged in politics >> reporter: northern virginia is also one of the most diverse areas of the u.s. hundreds of thousands of latinos and asian moved to the area since 1990 and are looking for their views to be reflected in government. >> translation: previous presidents have a promise like

all, but then they don't fulfil those promises. it would be excellent if they supported hispanic families more. >> reporter: they are political priorities that contrast with voters just a few kilometers south as one of the original states when the u.s. was formed, residents here believe protecting virginia's world conservative heritage is a priority >> it comes from a very christian background. there are farmers here, there are a lot of small businesses. people are fairly conservative in the area. >> reporter: such contrast in such close proximity, according to political scientist is what makes virginia a true political battleground state >> in other parts of the state where you actually have many of these frustrated whites are economically populous, you also have african americans throughout the south. who feel disenfranchised by the

system >> reporter: prior to 2008 republicans won virginia in elections. in 2008 and 2012 democratic candidate obama won by small minorities. >> i think you're going to see a contested battle on both sides of the aisle for this state because one of the things the candidates want to do is say to essentially their supporters, look, i won virginia in the primary. that would mean that i would be a very compelling general election candidate. >> reporter: that's why virginia voters in 2016 were some of the most sought after in the state's presidential nominating contest argentina and its main creditors have now reached a multi billion dollar agreement to settle a 14-year debt dispute. the settlement could help the country see it's economy become

better venezuelan petrol has been increased. many workers can't afford even the basics. >> reporter: for this man a practising lawyer, the only way to safeguard his life savings is to buy cars. in the inflationary economy a toxic mix of devaluation and triple digit inflation means that cash is worthless. assets like used cars which are negotiated in dollars have become a way to save money. >> translation: one has to find alternatives to avoid seeing what you have evaporate. >> reporter: the government is increasing the minimum wage from roughly $9 at the country's widely used black market rate to 14. for most people hiking their wage will make no difference.

a clean sign of an inflationary economy is printing inorganic money. this is the equivalent of the basic food basket. this constitutes the basic minimum wage. this represent is worth this much. buying cars works for the middle-class. but what are those who earn minimum wage doing? in these bare brick homes in the hills most are only just getting by. this man says he has began to skip meals. >> translation: it's hard. we are living through things in this country that we had never seen before. >> reporter: shopping at this government-run food shops could get him more value for his money, but basic goods can hardly ever been found and he will have to skip on work while he stands in line for hours. >> translation: with this

triple inflation what we're seeing is the shrinking of people's purchasing power. >> reporter: back here the entrepreneur explains more of what for most would seem counter intuitive economic logic. this yellow car cost him $1,000 three years ago. today he says he can get 4500. >> translation: in this street i've managed to set up my own personal bank >> reporter: inflation is for most countries a thing of the past. in venezuela, however, it proves that the rich get richer and the poor get poorer and go hungry an american and russian are expected to return to earth on wednesday after spending a record 340 days on board the international space station. their physical and mental condition will be closely examined as part of the n.a.s.a.'s plan to send a

mission to marchs. >> congratulations for your year have assists >> reporter: two have taken more than 5400 spins around the earth, taking part in six space walks and carried out experiments that included growingedible vegetables in zero gravity conditions. it is how their own bodies have weathered the long spell of radiation exposure and weightlessness that will be examined the most. he says he feel fine but has a keener sense of the isolation of travel. spending half the time of a box half the sign of a booth, he points out the challenges that could take 500 days or more. >> making that private area perfect as possible, i think will go a long way towards reducing fatigue, reducing

stress. >> reporter: while scientists will collect data from both these two, it is the american who will be subject to closer examination. together with his idea at all twin brother, retired astronaut mark. >> so far my role has been to provide samples, blood, saliva, other things i'm not going to go into, and be there for mris and ultrasounds. >> reporter: the two will be compared for changes to their vision and their system, and the chromosom chromosomes. >> we're using the latest technology for sequencing to really identify each t cells in mark and scott and try to see them react. >> reporter: he said he could have spent another year on the space station if necessary, but back on the ground he will
