RAF Typhoon FGR4s have conducted a mission with French warplanes in a joint strike against an subterranean weapons facility in Syria used by the Daesh militant organization, per a report from the UK Ministry of Defence.
The facility, identified by reconnaissance, was believed to be storing arms and explosives, the statement said, and was situated in hills just north of the ancient city of Palmyra in central Syria.
"The RAF jets used precision-guided Paveway IV munitions to target a number of entry passages down to the facility... preliminary assessments suggest the objective was successfully hit," officials stated.
There was no sign of any harm to civilians in the operation conducted Saturday night and each participating jet made a safe return, the ministry further stated.
The British jets were supported by a Voyager aerial refuelling aircraft.
Daesh - referred to as the so-called Islamic State - imposed jihadist rule over significant areas in Iraq and Syria until 2019.
"This action shows British leadership, and resolve to stand shoulder to shoulder with our partners, to eradicate any re-emergence of the terrorist group and their violent and radical beliefs in the region," the British Defence Secretary John Healey said.
RAF aircraft have conducted surveillance missions over Syrian airspace to "deter any efforts to regroup" of the group subsequent to its defeat at the Baghuz confrontation in 2019, the MoD reported.
"I must thank all the members of the UK armed forces participating in this mission for their professionalism and their valour," he commented. "Including them were thousands of British personnel deployed over the festive period. This operation, to take out militants who threaten our way of life, demonstrates how our armed forces are always on standby, continuously, keeping Britain secure at home and powerful internationally."
During December, the US military conducted what it termed a "massive strike" targeting Daesh sites in the country, following an ambush resulted in the deaths of two American soldiers and a local interpreter in the Palmyra area.
The U.N. estimates Daesh still boasts between 5,000 and 7,000 fighters in both countries.
