British Prime Minister David Cameron said Thursday that there was limited but growing evidence that the regime of Syrian President Bashar Assad had used chemical weapons in Syria.
Speaking in a BBC interview, Cameron called the likely use of chemical weapons in Syria, "extremely serious, this is a war crime, and we should take it very seriously."
He agreed with US President Barack Obama's assertion that the use of chemical weapons was a "red line," but said that Britain was trying not to make the mistake of rushing to judgment without verifying the evidence.
Cameron stated that he would not like to see British troops on the ground in Syria, but he does support increasing pressure on the Assad regime.
"I have always been keen for us to do more. We are working with the opposition, we want our allies and partners to do more with us to shape that opposition to make sure we are supporting people with good motives who want a good outcome, to put pressure on that regime so we can bring it to an end."
