French jets bomb Syria in the ISIS stronghold of Raqqa

French fighter jets bombed a series of ISIS sites in Raqqa, Syria, on Sunday in what officials described as a major bombardment.

The targets included a command center, a recruitment center, an ammunition storage base and a training camp for the terror group, said Mickael Soria, press adviser for France's defense minister.

Paris attacks: Authorities hunt for a French national

ISIS claims Raqqa as the capital of its so-called caliphate. The airstrikes come two days after a series of terrorist attacks in Paris on Friday. ISIS has claimed responsibility for the attacks, which France's President described as "an act of war."

Twelve aircraft, including 10 fighter jets, were involved in Sunday's airstrikes, Soria said.

Twenty bombs were dropped, he said, and all of the targets were destroyed.
