France has launched a massive air strikes on ISIS stronghold of Raqqa following Paris attacks 41611151.

Twelve aircraft, including 10 fighter jets, dropped a total of 20 bombs in the biggest air strikes since France extended its bombing campaign against the extremist group to Syria in September, the defence ministry said.

The jets were launched from sites in Jordan and the Persian Gulf, in co-ordination with US forces. The operation struck a command centre, recruitment centre for jihadists, a munitions depot, and a training camp for fighters. The sites targeted had previously been identified on reconnaissance flights, the statement said.

A defence official was quoted by Associated Press as saying the strikes were “massive” and had destroyed two jihadi sites in Raqqa.

“The first target destroyed was used by Daesh as a command post, jihadist recruitment centre and arms and munitions depot. The second held a terrorist training camp,” a ministry statement said.

Reports from activists inside Raqqa suggest the airstrike targets were known Isis strongholds, including Division 17, an army base to the north of the city that had been under Isis control since July 2014.

In the meanwhile, French police have launched an international hunt for a Belgian-born man they believe helped organize the assaults with two of his brothers. One of the brothers died in the attacks, while the second is under arrest in Belgium, a judicial source said.
