French war planes pounded the so-called Islamic State group's de facto Syrian capital Raqqa, destroying a command post and a training camp, the French Defence Ministry said.
In its first air strike against IS since the string of deadly Paris attacks claimed by the jihadist group, 12 war planes, including 10 fighter bombers, dropped 20 bombs on the targets.
"The first target destroyed was used by Daesh (an Arabic acronym for IS) as a command post, jihadist recruitment centre and arms and munitions depot. The second held a terrorist training camp," a ministry statement said.
The planes left from Jordan and the United Arab Emirates and the operation was conducted in coordination with American forces, the ministry said.
French President Francois Hollande on Saturday blamed the Islamic State group for the gun and suicide attacks that left at least 129 dead in Paris on Friday, calling the attacks an "act of war".
Meanwhile new Canadian Prime Minister Justin Trudeau today faced the dilemma of whether to make good on a campaign pledge to halt air strikes against the Islamic State group.
Mr Trudeau, who was at the G-20 summit in Turkey, now faces much tougher talk among the international community against IS.
And the Canadian opposition is firmly in support of the country remaining within the US-led coalition attacking IS fighters in Iraq and Syria.
At the G-20 meeting US President Barack Obama pledged to intensify the fight against IS in Syria.
Before he left for the G-20 Mr Trudeau said: "We'll continue to engage with our allies around the world in ensuring the safety of Canadians and others both here at home and around the world."
His position has drawn criticism from the Conservative opposition, which sent Canadian planes to the region while in power before Mr Trudeau.
Shortly after winning election in mid-October, Mr Trudeau told Mr Obama that Canada would stop attacking IS targets in Iraq and Syria. But he did not give a timetable for the halt.
Canada has been bombing IS positions in Iraq since October 2014, and broadened the offensive to Syria in April under the Conservative government of Stephen Harper.
