Britain's parliament has backed its Prime Minisiter David Cameron and voted to approve airstrikes against Islamic State militants in Iraq.
The vote, which was passed by 524 votes to 43, will pave the way for the Royal Air Force to join U.S.-led military action with immediate effect.
Ahead of his vote, Cameron appealed to lawmakers, the majority of whom voted against military action in Syria last year, asking them: "Is there a threat to the British people? The answer is yes."
He also did not rule out the possibility of further military action beyond initial plans for airstrikes - and added that he would be prepared to order immediate intervention to stop a humanitarian catastrophe, without the backing of MPs.
