An official says Jordan has launched dozens of air strikes against the Islamic State group since the militants released a video last week showing the killing of a Jordanian fighter pilot.

Jordan has said it would retaliate harshly for the slaying of the pilot, who was burned to death in a cage.

Jordan has been a member of a U.S.-led military coalition against the Islamic State group since September. After the release of the video, it said it would intensify bombing raids.

Since Thursday, Jordan has carried out daily attacks. Government spokesman Mohammed al-Momani said Sunday that Jordan has launched dozens of airstrikes since the pilot's death, without elaborating.

Meanwhile, another coalition member, the United Arab Emirates, says it is sending a squadron of F-16 fighters to Jordan.
