British Air Force Typhoon fighter aircraft have operated alongside France's air force in a combined operation on an subterranean weapons facility in Syrian territory employed by the Daesh militant organization, per a report from the UK's MoD.
The facility, pinpointed through surveillance, was thought to be housing weapons and explosive materials, the announcement noted, and was located in hills just north of the historic site of Palmyra in central Syria.
"Our aircraft employed laser-guided Paveway IV weapons to hit a number of entry passages leading to the site... preliminary assessments indicate the target was engaged successfully," the MoD said.
There was no evidence of any civilian casualties in the attack on Saturday evening and every plane involved returned safely, the MoD added.
The Typhoon fighters were assisted by a Voyager refuelling tanker.
Daesh - referred to as the so-called Islamic State - enforced jihadist rule over significant areas in both Syria and Iraq until 2019.
"This operation underscores the UK's leading role, and commitment to operate in unison with our allies, to stamp out any revival of IS and their dangerous and violent ideologies in the area," the British Defence Secretary the Defence Secretary said.
UK warplanes have performed surveillance missions over Syrian airspace to "deter any attempted resurgence" of Islamic State subsequent to its military defeat at the battle of Baghuz in 2019, the ministry said.
"I want to thank every member of the UK armed forces who took part in this mission for their professionalism and their valour," he added. "Including them were a great many British personnel on duty over the festive period. This operation, to remove terrorist threats who pose a risk to our security, shows how UK forces are prepared to act, throughout the year, ensuring Britain's security within its borders and strong abroad."
In December, the United States armed forces conducted what it called a "massive strike" on Daesh sites in Syria, following an assault claimed the lives of two US troops and a civilian interpreter in the Palmyra area.
The U.N. reports IS still boasts an estimated 5,000 to 7,000 fighters in Syria and Iraq.
