France has begun air strikes against so-called Islamic State in Iraq from the aircraft carrier Charles de Gaulle, reports say, reports the BBC.
A number of Rafale fighter planes took off from the carrier early on Friday, news agency AFP said.
It quoted an officer on board, who said the planes would take part in an attack on Mosul, an IS stronghold in Iraq.
The Charles de Gaulle, France's only aircraft carrier, was sent to the region earlier in September.
Iraqi forces have gained significant ground in the battle for Mosul, which was occupied by IS in June 2014, and are expected to launch an offensive to retake the city soon.
French radio station RTL reported that 24 aircraft will take part in today's operation, with a sortie every three minutes, on average.
