Jordan has launched 56 airstrikes against Islamic State group weapons depots, training centers and military barracks since militants released a video of them burning a Jordanian pilot to death, Jordan's air force chief said Sunday.
Meanwhile, a squadron of F-16 fighter jets from the United Arab Emirates arrived in Jordan. The UAE has said it is sending the warplane to support the kingdom, and a Jordanian government official has said they will participate in airstrikes on Islamic State group targets.
