RAF Typhoon jets have operated alongside France's air force in a coordinated attack on an subterranean weapons facility in Syria used by the Islamic State group (IS), per a report from the UK Ministry of Defence.
The location, located using surveillance, was believed to be housing weapons and explosive materials, the statement said, and was situated in hills just to the north of the historic site of Palmyra in central Syria.
"Our fighter planes employed laser-guided Paveway IV weapons to strike a several access tunnels providing entry to the facility... early reports indicate the objective was successfully hit," the MoD said.
There was no evidence of any harm to civilians in the attack on Saturday evening and all the aircraft made a safe return, the defence officials confirmed.
The Typhoon fighters were backed up by a Voyager aerial refuelling aircraft.
Daesh - alternatively referred to as the so-called Islamic State - imposed militant control over large swathes of Syria and Iraq prior to its 2019 collapse.
"This action underscores our UK leadership, and resolve to stand shoulder to shoulder with allied nations, to eradicate any revival of Daesh and their dangerous and violent ideologies in the region," the British Defence Secretary the minister said.
RAF aircraft have carried out patrols over Syrian airspace to "prevent any efforts to regroup" of IS following its routing at the battle of Baghuz in the year 2019, the MoD reported.
"I want to thank all the members of British forces participating in this operation for their professionalism and their valour," the Defence Secretary said. "They were among numerous UK service members on duty over the festive period. This operation, to remove terrorist threats who pose a risk to our security, shows how UK forces are always on standby, all year round, protecting the UK domestically and strong abroad."
During December, the United States armed forces executed what it termed a "large-scale strike" on Islamic State objectives in the country, after an attack resulted in the deaths of two American soldiers and a local interpreter in Palmyra.
The UN reports IS still maintains an estimated 5,000 to 7,000 fighters in both countries.
