Royal Air Force Typhoon FGR4s have conducted a mission with France's air force in a coordinated attack against an underground arms cache in Syrian territory used by the Daesh militant organization, according to the UK Ministry of Defence.
The facility, located using intelligence, was assessed as housing weapons and explosive materials, the announcement noted, and was located in mountains just north of Palmyra in central Syria.
"The RAF jets employed Paveway IV guided bombs to hit a number of access tunnels leading to the site... preliminary assessments suggest the objective was successfully hit," the MoD said.
There was no evidence of any civilian impact in the strike conducted Saturday night and every plane involved returned to base without incident, the MoD added.
The Typhoon FGR4s were assisted by a Voyager refuelling tanker.
The Islamic State group - referred to as Daesh - imposed extremist governance over large swathes of both Syria and Iraq until 2019.
"This action shows British leadership, and resolve to work closely with our allies, to eliminate any revival of IS and their dangerous and violent ideologies in the Middle East," UK Defence Secretary the Defence Secretary remarked.
British military aircraft have carried out overwatch operations over Syrian airspace to "prevent any attempted resurgence" of Islamic State after its routing at the Baghuz confrontation in 2019, the authorities noted.
"I want to thank every member of the UK armed forces involved in this operation for their professionalism and their valour," the Defence Secretary commented. "They were among a great many UK service members deployed over Christmas and New Year. This action, to eliminate militants who endanger our safety, highlights how British military are prepared to act, all year round, keeping Britain secure at home and influential overseas."
In December, the US military conducted what it called a "large-scale strike" against Daesh sites in Syria, subsequent to an assault resulted in the deaths of two American soldiers and a civilian linguist in Palmyra.
The UN estimates Daesh still maintains an estimated 5,000 to 7,000 militants in Syria and Iraq.
