says allies president of the United States "could not allow the use of chemical weapons," but goes on to say the red line has been crossed
President Barack Obama warned on Friday that the Syrian regime test had used chemical weapons against the civilian population would be a "game changer", but warned that more evidence is needed.
Speaking at the White House, Obama said the confirmation of President Bashar al-Assad had deployed chemical agents in the long civil war in Syria would change "calculation" of his government, but n has not said "red line" was crossed.
Barack Obama's cautious comments reflect a lack of consensus in Washington on how to respond to claims that Syria has used sarin gas in the recent incidents. Members informed by the Secretary of State John Kerry Congress Friday said the most likely option would be to other countries specific armed rebel groups.
Sitting alongside King Abdullah of Jordan at the White House, Obama said the international community "can not stand aside and allow the systematic use of weapons such as guns chemical against the civilian population. "
But he left open the possibility of use in Syria untested: "I think, in many ways, a line has been crossed when we see tens of thousands of innocent people killed by a diet
"But the use of chemical weapons and the dangers it poses to the international community, neighboring countries of Syria, the potential of chemical weapons falling into the hands of terrorists - all things add up each more urgent which is already a major security and humanitarian problems in the region. "
On Thursday, the White House said that U.S. intelligence concluded with "varying degrees of" the Syrian government used chemical weapons twice confidence. British authorities claim that there are evidence of sarin use in at least three incidents of Khan al-Assal, near Aleppo, Homs and near Damascus.
In London, British Prime Minister David Cameron described the testing of chemical weapons used as "small but growing" and downplayed any suggestion of British troops could be deployed in Syria as a result, would only say that this is a red line for the international community to "do more."
Speaking to the BBC, Cameron echoed the caution of the White House on the evidence so far, saying that the British government not to make the mistake of "rush into print" and will work to verify the evidence with its allies.
"It is very worrying that we see. Evidence is limited, but there is increasing evidence that there has been too much on the use of chemical weapons, probably by the regime, "said Cameron." This is serious - it is a war crime. - And you have to take very seriously, "
also left well short of suggesting that the confirmation of the use of chemical weapons necessarily produce military action. "I think that President Obama said was absolutely right -. That the international community should be a red line for us to do more"He added: "I want to be absolutely clear, I think the lesson of Iraq should be the way we go and use of information and intelligence, and I think this lesson has been learned, but I think it is very important for politicians., and leaders of this generation to look at what is happening in Syria and ask ourselves what we can do. " In the incident al-Assal Khan 19 March, the Syrian government and the rebels have claimed that chemical agents were used against him. British officials say the troops of the Syrian army appears to have been affected in this incident, but suggested that he was one and another case of "friendly fire", a stray bullet, or deliberate attempt to engage the rebels.
