What they said... MPs lock horns in Commons
"I believe the House has taken the right decision to keep the UK safe: action in Syria as part of a broader strategy."
PM David Cameron
"Since the beginning of the counter-Isil campaign, the UK has been one of our most valued partners. We look forward to having British forces flying over Syria, and will work to integrate them into our coalition air tasking orders as quickly as possible."
US President Barack Obama
"Do we send in the bombers, not totally aware of what all the consequences are going to be, or do we pause, not send them in, and instead put all of our efforts into bringing about a peaceful, humanitarian and just political settlement for the people in Syria?"
Labour's Jeremy Corbyn
"There is agreement across this House the threat from Daesh (IS) is real and doing nothing is not an option. But there is no shortage of countries currently bombing in Syria. The point is, there is bombing currently under way in Syria and to pretend that what is being proposed while not taking that into account is highly misleading."
SNP Westminster leader Angus Robertson
"I believe we have a moral and practical duty to extend the action to Syria. I share the concerns expressed about potential civilian casualties. However, unlike Daesh none of us will act today with the intent to harm civilians, rather, we act to protect civilians from Daesh who target innocent civilians."
Shadow Foreign Secretary Hilary Benn
"I am not going to be a party to killing innocent civilians for what will be a gesture."
Labour MP and Father of House Sir Gerald Kaufman
