David Cameron urges MPs to back air strikes 'to keep Britain safe'

Cameron Seeks Backing to Bomb Islamic State in Syria

David Cameron has appealed to MPs to back RAF air strikes against Islamic State in its Syrian heartlands to "keep the British people safe" from the threat of terrorist attack.

Opening a 10-hour Commons debate ahead of a vote tonight, the Prime Minister said the country had no choice but to engage in the struggle with IS - also referred to Isil, Isis or Daesh.

"The question before the House today is how we keep the British people safe from the threat posed by Isil," he told MPs.

"This is not about whether we want to fight terrorism, it's about how best we do that."
