♪ it has been a week since the u.s. president told the world he would take military action on syria but there is opposition to military strike at the g-20 summit at the world's richest nations in russia. we now go to st. petersburg where that is taking place and peter sharp is standing by. and as we see along with the economic and financial agenda, barack obama was at the summit, also pushed for support for intervention in syria, how has he done with that? >> well, really the whole war clouds over syria is totally eclipsed what should have been a solid economic conference. if president obama felt this was going to be easy he will have been mistaken and it was always going to be a hard sell and the president has faced real difficulties in persuading members of the g-20 that their

interests lie in supporting a u.s. strike against syria. in fact, the only countries that he can rely on within the g-20 who would approve military action by america would be france and turkey and saudia arabia and he will return to washington later a disappointed man. >> reporter: and, peter, we are also hearing that russia is sending more war ships to the mediterranean and what can you tell us about that? >> the missile crews are heading in from the atlantic to join the existing russian fleet but is as it always is on stand by off that part of the eastern mediterranean, the russian defense ministry are at pains to point out it's not a result of the build up of the crisis, this is a regular deployment and regular rotation of vessels in

the area. of course there is a sizable presence of the american six fleet in the area with five crews missile carries destroyers but russians point out this is not in reaction to that. but obviously i mean it's a chance for the russians to fly the flag and remind the americans that the eastern mediterranean is not just their pawn. >> reporter: peter sharp, d-20 summit in st. petersburg, thank you. and we go to live pictures of the summit right now. there we go. we see barack obama speaking to david cameron. this is the final day of meetings and of course the main agenda of the summit is economic, the economy and financial issues. but of course much of that has been overshadowed by the push for intervention in syria and we will get you more as the day develops. well republic senator john mccain is heckled about giving a

speech about syria. and many in the audience in phoenix objected to his support for military strike. so according to polling most americans are against military action and barack obama is facing an up hill battle to get the support he wants from congress and the white house correspondent patty takes a look at the president's options. >> reporter: the majority of the american people are telling people they don't want the u.s. to intervene in syria. even if chemical weapons were used. >> we will do again is create another problem so we need to stop. >> reporter: the message being sent in town hall meetings and calls to their washington offices. >> let the senator know you are opposed to intervening syria. >> reporter: and swaying some elected leaders especially the house of representatives where it shows 49 representatives leaning to a yes vote, 199 no. but what are the repercussions

for the president if he can't get congress to approve a strike? he has been very careful with his words, not saying either way what he will do. >> but i did not take this to congress just because it's an empty exercise and it's important to have congress's support on it. >> reporter: the war powers act says the president can only use military force if there is a declaration of war. statutory authorization from congress or in the case of an emergency if the u.s. is attacked. but that law is often ignored ignored who usually ask for permission after they attack and bill clinton had senate approval before launching planes and missiles and later p authorization did not pass the house. >> to prevent it. >> reporter: the difference clinton had the backing of the u.n. and obama does not. still the president could act even if congress says, no. >> it wouldn't surprise me in the slightest if he went ahead

even without congressional approval. obviously there would be an avalanche of criticism and the public which is strongly opposed would be more strongly oppose and suspect it would take ten points off his popularity but if you are never up for election again why does it matter. >> reporter: it matters because with low popularity his second term agenda likely stalls and could face impeachment proceedings in the house if it is unlikely the senate would agree. without congress he would pay a price for acting, his aids are working hard behind the scenes to make sure he won't have to make that decision. patty al jazeera washington. >> reporter: american and british spy agencies cracked encryption systems designed to protect information on line according to newspapers the guardian and "new york times" and say they got the information from documents leaked by the whistle lower edward snow den and rob reynolds as the report.

the nsa i think that is focused a lot of attention on this and i think that the pew poll shows that people are increasingly concerned. >> reporter: the nsa appears to believe its code breaking abouts are a trump card in rivalries with russia, china and other countries. in the future, one document states super powers will be made or broken based on the strength of their cripto-analytic programs and rob reynolds with al jazeera. >> the dutch supreme court said the neither lands should be held for the massacre and they were ordered to leave a u.n. compound by peace keeping troops and could impact future un peace keeping missions. now kenya voted in favor of pulling out of the international criminal court. the president are due to go on trial for crimes against

including those against the president and his deputy. >> there has been considerable effort by part of the political class through propaganda and messaging to discredit their institutional and functional credibility and integrity of the icc. >> reporter: and the international criminal court's popularity has been declining in the country there are those who are saying this is all political and that the bigger picture has been forgotten, the crimes against humanity were committed and someone has to be accountable. this group listened closely to the parliamentary debate and they are post election balance that took place in 2008 when more than a thousand people died and she was raped by a policeman. . >> translator: we have been forgotten to expect anything to change as the case is referred

for the massachusetts technology institute and after examining photos from the scene he believes this was a new design of rocket carrying more of the deadly sarin than other experts suggested. >> they are looking for a russian war head or whatever. and this is not -- this is a designed war head that is unfortunately very cleverly thought out and very effective and very deadly. >> reporter: and there is more of the sarin than you would expect, how much? >> probably between 10-20 times more than people were thinking. >> that is why it killed so many people. >> probably that is the reason. >> there are people who say that you have not analyzed any of the actual samples themselves, this is an assessment from a far rather than scientific proof. >> the evidence is very clear, we have carcuss on the ground that have small craters next to them which would have been created by the small amount of explosion -- explosives used to

only god, only god will help us, no one else will. >> reporter: and despite the threat of a possible u.s. military strike, the number of people going in and out of syria is increasing. turkey is now home to almost half a million civilian refugees. the camp you see behind me has reached its limits with more than 32000 refugees living inside. this means when you come like this people cannot get in and this has become their home. just across the road inside the camp, the conditions are better and families live inside caravans and considered lucky to have found a shelter and the minimum to preserve their dignity. many here welcome the possible strike against syria but there is deep suspicion of the real intent. >> translator: i'm not sure if the west was sincerely sent by us. i fear the strike won't be aimed at the regime and maybe they

will strike the revolution and regime sites as well. >> reporter: the final decision to launch a strike is up to the u.s. congress and president obama. far away from the misery of these people. its effect however could either end or worsen the plight of millions of syrians. now the syrian opposition are calling on the international community and the organizations and regional countries to give more aid to the syrian refugees because their number is now over 2 million people. the opposition are saying half of the syrian population has turned into victims by their own countries. >> we are live and thank you. they are finding itself in the hot seat because of the nuclear crisis in fukushima and it defended experts after
