Canada's parliament has voted to authorise air strikes against Islamic State militants in Iraq following a US request.
Prime Minister Stephen Harper's Conservative Party introduced the motion last week and it was debated this week.
Harper has a majority of seats in parliament so the vote was all but assured.
The motion passed 157-134 on Tuesday.
The motion authorises air strikes in Iraq for up to six months and explicitly states that no ground troops be used in combat operations.

The combat mission includes up to six CF-18 fighter jets, a refuelling tanker aircraft, two surveillance planes and one airlift aircraft.
About 600 airmen and airwomen will be involved.
Canada is among dozens of countries that have joined the US-led coalition fighting the Islamic State militant group.
Both the opposition New Democrats and Liberals voted against the motion in parliament, saying they fear the mission could become a quagmire.
Harper has ruled out sending ground combat troops but 69 special forces soldiers already on the ground will continue to advise security forces fighting IS in the northern part of Iraq.
The White House welcomed Canada's decision.
"The United States welcomes the Canadian government's deployment of fighter and refuelling aircraft, as well as intelligence, surveillance and reconnaissance aircraft to participate in the campaign to degrade and destroy ISIL in Iraq," a White House spokesman said.
"Canadians and Americans have fought alongside each other in several major conflicts over the past century, and we are grateful for Canada's further contribution against terrorism," the spokesman added.
The military mission is supported by 64 per cent of Canadians, according to a poll published by the daily Globe and Mail.
