MUWAFFAQ AL-SALTI AIR BASE, Jordan — ISIS leader Abu Bakr al-Baghdadi is running scared as a result of an intensified bombing campaign brought on by the murder of a Jordanian pilot, the head of the country's air force said.

"He is frightened by what we did in the last three days," Maj. Gen. Mansour al-Jabour told NBC News on Sunday. "We will not hesitate" to kill al-Baghdadi, he said. "He is going to be on top of our list."
