Royal Air Force Typhoon FGR4s have conducted a mission with France's air force in a joint strike on an underground arms cache in Syrian territory employed by the IS group, as stated by the UK Ministry of Defence.
The facility, identified by reconnaissance, was believed to be containing munitions and bombs, the announcement noted, and was positioned in hills just above the ancient city of Palmyra in Syria's central region.
"Our fighter planes used precision-guided Paveway IV munitions to strike a number of access tunnels providing entry to the facility... preliminary assessments indicate the target was engaged successfully," the ministry announced.
There was no evidence of any civilian casualties in the attack conducted Saturday night and all the aircraft returned safely, the MoD added.
The Typhoon FGR4s were backed up by a Voyager aerial refuelling aircraft.
IS - alternatively referred to as ISIS - imposed extremist governance over large swathes of Iraq and Syria prior to its 2019 collapse.
"This operation underscores the UK's leading role, and resolve to work closely with our partners, to eradicate any revival of IS and their dangerous and violent ideologies in the region," Britain's Defence Chief the minister remarked.
UK warplanes have conducted surveillance missions over Syria to "prevent any attempted resurgence" of IS following its routing at the climactic battle in Baghuz in the year 2019, the MoD reported.
"I must thank all the members of our armed forces who took part in this operation for their skill and their courage," the Defence Secretary added. "They were part of a great many UK service members stationed over the festive period. This mission, to take out dangerous terrorists who endanger our safety, shows how UK forces are always on standby, continuously, keeping Britain secure within its borders and strong abroad."
Last December, the United States armed forces conducted what it termed a "large-scale strike" on Daesh sites in Syria, following an attack resulted in the deaths of two American soldiers and a local interpreter in Palmyra.
The UN estimates Islamic State still maintains between 5,000 and 7,000 fighters in Syria and Iraq.
