France has launched airstrikes on the Daesh-held city of Raqqa in "self defence" of the deadly attacks in Paris that claimed 132 lives.

France's defence ministry confirmed 12 warplanes, including 10 bombers, dropped 20 bombs on the stronghold that has served as the defacto Daesh capital.

The bombing struck a command-and-control centre, a training facility, recruitment building and a munitions depot.

Speaking in Turkey where world leaders have gathered for a meeting of the G20, French Foreign Minister Laurent Fabius described the bombing as an act of "self defence".

"That's what we did today with the strikes on Raqqa. We can't let Daesh (IS) attack without a reaction,"

The French defence ministry announced the attack earlier, saying in a statement the "first target destroyed was used by Daesh as a command post, recruitment centre and arms and munitions depot".

The attacks were conducted in co-ordination with American forces, the ministry said.

French President Francois Hollande on Saturday blamed the Daesh group for the gun and suicide attacks that left 132 dead in Paris on Friday, calling them an "act of war".
