The facility, identified by intelligence, was believed to be containing munitions and bombs, the statement said, and was situated in hills just north of Palmyra in the heart of Syria.
"Our aircraft utilized Paveway IV guided bombs to target a series of approach shafts leading to the site... early reports are that the target was engaged successfully," the MoD said.
