French aircraft hit targets in Syria in early October 2015 . French Prime Minister Valls told reporters in Amman , Jordan , " Terrorist attacks have taken place ( in France ) ... In the name of self-defence it is obligatory to strike Daesh and we will continue , " and " Whether there are French ( citizens ) among them , it 's possible , but we have a responsibility to hit Daesh . Terrorists do not have passports . " On 14 November 2015 , ISIL claimed that the 13 November 2015 Paris terrorist attacks were retaliation for Opération Chammal . In response , the French forces increased their attacks . On 15 November 2015 , the French Air Force launched its largest airstrike of the bombing campaign sending 12 planes , including 10 fighters , that dropped 20 bombs in training camps and ammunition facilities in Raqqa , Syria , the '' de facto '' capital of ISIL . The UK offered support with air-to-air refuelling and use of its air base in Cyprus , RAF Akrotiri . Also Germany intervened in reaction to the Paris attacks and assisted France by sending a frigate and Panavia Tornado reconnaissance aircraft to Turkey
