RAF Typhoon jets have joined forces with French warplanes in a coordinated attack targeting an hidden munitions depot in Syrian territory employed by the IS group, according to the UK Ministry of Defence.
The location, located using intelligence, was assessed as storing arms and explosives, the announcement noted, and was situated in hills just to the north of the historic site of Palmyra in Syria's central region.
"Our fighter planes employed precision-guided Paveway IV munitions to hit a several approach shafts down to the site... initial indications indicate the objective was successfully hit," the ministry announced.
There was no indication of any civilian impact in the operation on Saturday evening and every plane involved returned to base without incident, the ministry further stated.
The British jets were backed up by a Voyager aerial refuelling aircraft.
The Islamic State group - also known as the so-called Islamic State - imposed militant control over parts of Iraq and Syria until 2019.
"This strike shows the UK's leading role, and determination to operate in unison with our allies, to eradicate any re-emergence of IS and their violent and radical beliefs in the region," UK Defence Secretary the Defence Secretary stated.
British military aircraft have conducted patrols over Syrian airspace to "deter any efforts to regroup" of IS following its routing at the climactic battle in Baghuz in 2019, the authorities noted.
"I must thank all the members of the UK armed forces participating in this strike for their skill and their valour," he commented. "Including them were numerous British troops deployed over the holidays. This action, to take out terrorist threats who threaten our security, shows how British military are always on standby, continuously, keeping Britain secure at home and powerful internationally."
During December, the US military executed what it called a "massive strike" on Daesh sites in the country, following an ambush claimed the lives of two American soldiers and a civilian interpreter in Palmyra.
The UN reports Islamic State still has an estimated 5,000 to 7,000 combatants in both countries.
