Royal Air Force Typhoon jets have joined forces with France's air force in a combined operation against an hidden munitions depot in Syria used by the IS group, as stated by the UK Ministry of Defence.
The facility, located using intelligence, was thought to be containing munitions and bombs, the announcement noted, and was positioned in mountains just above Palmyra in Syria's central region.
"The RAF jets used precision-guided Paveway IV munitions to target a number of entry passages leading to the depot... preliminary assessments suggest the objective was successfully hit," officials stated.
There was no sign of any civilian casualties in the attack on Saturday evening and each participating jet returned to base without incident, the MoD added.
The Typhoon fighters were backed up by a Voyager aerial refuelling aircraft.
The Islamic State group - also known as ISIS - enforced extremist governance over large swathes of Iraq and Syria prior to its 2019 collapse.
"This strike underscores the UK's leading role, and resolve to stand shoulder to shoulder with allied nations, to eradicate any resurgence of IS and their dangerous and violent ideologies in the region," the British Defence Secretary the Defence Secretary remarked.
UK warplanes have performed patrols over Syrian airspace to "prevent any attempted comeback" of the group subsequent to its defeat at the climactic battle in Baghuz in 2019, the ministry said.
"I extend gratitude to all the members of our armed forces participating in this operation for their professionalism and their bravery," Healey said. "Including them were numerous British troops on duty over the festive period. This operation, to remove terrorist threats who threaten our way of life, demonstrates how UK forces are always on standby, throughout the year, protecting the UK domestically and powerful internationally."
Last December, the US military executed what it called a "major assault" targeting Daesh sites in Syria, following an assault killed two US troops and a civilian interpreter in Palmyra.
The U.N. says Daesh still maintains an estimated 5,000 to 7,000 militants in Syria and Iraq.
