British lawmakers have voted against military intervention in Syria.
The vote has comes as a major setback for both British Prime Minister David Cameron and the Obama administration, who wanted to punish the Assad regime for an alleged chemical weapons strike.
According to Fox News, Cameron, who has been aligned with Obama in advocating a tough response, indicated after the vote that he would abide by the outcome.
A strike on Syria was narrowly defeated, by 285 votes to 272 votes.
The outcome raises serious questions for Obama, who has not yet made a decision on the way forward in Syria, but had indicated his administration would need international support for any strike, the report said.
According to the report after failing to win support for an anti-Assad resolution before the UN Security Council, US officials were looking to allies like Britain and France to build a coalition for action in Syria.
The White House said after the vote that it would continue to assess its options on Syria.
