Royal Air Force Typhoon FGR4s have conducted a mission with French warplanes in a combined operation targeting an hidden munitions depot in Syria operated by the Daesh militant organization, per a report from the UK's MoD.
The facility, located using intelligence, was believed to be storing arms and explosives, the announcement noted, and was positioned in mountainous terrain just to the north of the ancient city of Palmyra in Syria's central region.
"Our fighter planes used laser-guided Paveway IV weapons to hit a several access tunnels leading to the site... preliminary assessments are that the strike was effective," the MoD said.
There was no indication of any civilian impact in the attack conducted Saturday night and each participating jet returned to base without incident, the ministry further stated.
The Typhoon fighters were supported by a Voyager refuelling tanker.
IS - referred to as Daesh - imposed militant control over significant areas in Syria and Iraq until 2019.
"This action demonstrates British leadership, and determination to stand shoulder to shoulder with allied nations, to eliminate any revival of Daesh and their dangerous and violent ideologies in the region," the British Defence Secretary the minister said.
UK warplanes have performed surveillance missions over Syrian airspace to "deter any efforts to regroup" of Islamic State subsequent to its military defeat at the battle of Baghuz in 2019, the MoD reported.
"I must thank all the members of our armed forces involved in this operation for their professionalism and their courage," he commented. "Including them were a great many British personnel on duty over Christmas and New Year. This mission, to eliminate terrorist threats who endanger our security, shows how our armed forces are always on standby, all year round, ensuring Britain's security at home and strong abroad."
Last December, the United States armed forces carried out what it described as a "major assault" targeting Daesh sites in the country, following an assault resulted in the deaths of two US servicemembers and a civilian linguist in Palmyra.
The United Nations says Daesh still boasts between 5,000 and 7,000 militants in both countries.
