British Air Force Typhoon FGR4s have conducted a mission with France's air force in a joint strike targeting an subterranean weapons facility in Syria used by the Islamic State group (IS), as stated by the UK's MoD.
The facility, located using intelligence, was assessed as storing arms and explosives, the announcement noted, and was situated in hills just to the north of Palmyra in central Syria.
"The RAF jets used Paveway IV guided bombs to target a number of access tunnels leading to the depot... preliminary assessments indicate the objective was successfully hit," officials stated.
There was no indication of any harm to civilians in the attack conducted Saturday night and all the aircraft returned safely, the ministry further stated.
The Typhoon fighters were supported by a Voyager tanker plane.

"They were part of a great many British troops deployed over the festive period. This action, to remove militants who threaten our way of life, highlights how UK forces are prepared to act, continuously, keeping Britain secure domestically and strong abroad."
