RAF Typhoon fighter aircraft have joined forces with French aircraft in a combined operation targeting an subterranean weapons facility in Syria employed by the IS group, per a report from the British defence ministry.
The location, pinpointed through reconnaissance, was believed to be containing munitions and bombs, the release indicated, and was located in hills just above Palmyra in central Syria.
"The RAF jets utilized Paveway IV guided bombs to target a series of approach shafts leading to the site... preliminary assessments suggest the objective was successfully hit," the ministry announced.
There was no sign of any civilian impact in the strike conducted Saturday night and all the aircraft made a safe return, the MoD added.
The Typhoon FGR4s were assisted by a Voyager refuelling tanker.
IS - alternatively referred to as ISIS - imposed extremist governance over large swathes of Iraq and Syria before its territorial defeat in 2019.
"This strike shows the UK's leading role, and determination to operate in unison with our partners, to eliminate any revival of Daesh and their violent and radical beliefs in the Middle East," UK Defence Secretary the Defence Secretary remarked.
RAF aircraft have carried out patrols over Syrian airspace to "forestall any efforts to regroup" of Islamic State subsequent to its military defeat at the climactic battle in Baghuz in the year 2019, the ministry said.
"I want to thank all the members of our armed forces involved in this strike for their expertise and their bravery," the Defence Secretary said. "They were part of numerous UK service members stationed over the festive period. This action, to remove terrorist threats who pose a risk to our security, shows how our armed forces are always on standby, all year round, ensuring Britain's security at home and powerful internationally."
Last December, the US military conducted what it described as a "major assault" against Islamic State objectives in Syria, subsequent to an assault resulted in the deaths of two US troops and a civilian interpreter in Palmyra.
The United Nations reports IS still maintains roughly 5-7 thousand militants in both countries.
