British Air Force Typhoon FGR4s have conducted a mission with France's air force in a joint strike against an subterranean weapons facility in Syrian territory employed by the Islamic State group (IS), as stated by the British defence ministry.
The site, pinpointed through intelligence, was believed to be storing arms and explosives, the release indicated, and was situated in mountainous terrain just north of Palmyra in Syria's central region.
"Our fighter planes utilized Paveway IV guided bombs to target a series of access tunnels leading to the facility... early reports are that the objective was successfully hit," officials stated.
There was no sign of any civilian impact in the attack late on Saturday and each participating jet returned safely, the defence officials confirmed.
The British jets were backed up by a Voyager aerial refuelling aircraft.
