RAF Typhoon jets have operated alongside French aircraft in a combined operation targeting an subterranean weapons facility in Syrian territory employed by the IS group, per a report from the UK Ministry of Defence.
The location, located using surveillance, was believed to be storing arms and explosives, the statement said, and was situated in mountains just north of Palmyra in the heart of Syria.
"Our aircraft used precision-guided Paveway IV munitions to target a several approach shafts down to the depot... early reports indicate the objective was successfully hit," officials stated.
There was no indication of any harm to civilians in the attack on Saturday evening and every plane involved returned safely, the defence officials confirmed.
The Typhoon FGR4s were supported by a Voyager aerial refuelling aircraft.
IS - alternatively referred to as the so-called Islamic State - enforced jihadist rule over parts of Iraq and Syria before its territorial defeat in 2019.
"This action underscores our UK leadership, and determination to work closely with allied nations, to stamp out any revival of the terrorist group and their violent and radical beliefs in the area," Britain's Defence Chief the Defence Secretary stated.
British military aircraft have performed patrols over Syrian airspace to "prevent any attempted resurgence" of Islamic State after its military defeat at the battle of Baghuz in the year 2019, the ministry said.
"I extend gratitude to every member of British forces who took part in this mission for their professionalism and their courage," he said. "Including them were a great many British troops on duty over the festive period. This action, to remove terrorist threats who endanger our safety, shows how UK forces are ready to step up, throughout the year, ensuring Britain's security domestically and strong abroad."
During December, the United States armed forces conducted what it described as a "large-scale strike" on Daesh sites in the country, following an ambush resulted in the deaths of two US troops and a civilian linguist in Palmyra.
The U.N. reports Islamic State still maintains between 5,000 and 7,000 fighters in both countries.
