Royal Air Force Typhoon jets have conducted a mission with French warplanes in a combined operation on an subterranean weapons facility in Syrian territory employed by the IS group, per a report from the UK's MoD.
The facility, identified by reconnaissance, was thought to be housing weapons and explosive materials, the statement said, and was situated in hills just to the north of Palmyra in central Syria.
"The RAF jets used precision-guided Paveway IV munitions to target a several approach shafts leading to the facility... early reports are that the target was engaged successfully," officials stated.
There was no evidence of any civilian impact in the operation on Saturday evening and all the aircraft made a safe return, the MoD added.
The Typhoon fighters were backed up by a Voyager refuelling tanker.
Daesh - referred to as Daesh - imposed jihadist rule over parts of Syria and Iraq until 2019.
"This operation shows British leadership, and resolve to stand shoulder to shoulder with our partners, to eradicate any resurgence of the terrorist group and their dangerous and violent ideologies in the region," UK Defence Secretary the Defence Secretary said.
RAF aircraft have conducted surveillance missions over Syrian airspace to "prevent any attempted comeback" of IS subsequent to its routing at the climactic battle in Baghuz in 2019, the ministry said.
"I want to thank every member of British forces who took part in this operation for their skill and their valour," Healey said. "They were part of numerous British personnel stationed over the holidays. This action, to eliminate militants who endanger our safety, shows how British military are ready to step up, throughout the year, ensuring Britain's security domestically and influential overseas."
During December, the US military conducted what it described as a "massive strike" against IS targets in Syria, following an ambush claimed the lives of two American soldiers and a civilian interpreter in Palmyra.
The U.N. reports Islamic State still has an estimated 5,000 to 7,000 fighters in Syria and Iraq.
