RAF Typhoon FGR4s have operated alongside French warplanes in a combined operation on an hidden munitions depot in Syrian territory employed by the Islamic State group (IS), per a report from the UK's MoD.
The site, identified by intelligence, was believed to be housing weapons and explosive materials, the announcement noted, and was located in mountainous terrain just to the north of the ancient city of Palmyra in central Syria.
"Our fighter planes utilized laser-guided Paveway IV weapons to hit a several access tunnels providing entry to the facility... preliminary assessments indicate the target was engaged successfully," the MoD said.
There was no evidence of any civilian impact in the attack conducted Saturday night and all the aircraft made a safe return, the defence officials confirmed.
The British jets were assisted by a Voyager tanker plane.
Daesh - alternatively referred to as ISIS - established militant control over large swathes of Iraq and Syria until 2019.
"This operation underscores the UK's leading role, and resolve to work closely with our allies, to eradicate any resurgence of IS and their harmful and extremist ideologies in the area," UK Defence Secretary John Healey said.
UK warplanes have performed surveillance missions over Syria to "deter any attempted comeback" of the group after its defeat at the Baghuz confrontation in 2019, the ministry said.
"I must thank the personnel of the UK armed forces involved in this operation for their skill and their courage," Healey added. "They were part of numerous British personnel deployed over the holidays. This operation, to eliminate dangerous terrorists who threaten our safety, demonstrates how British military are prepared to act, continuously, ensuring Britain's security domestically and strong abroad."
During December, the US military conducted what it called a "massive strike" against Daesh sites in the country, after an attack resulted in the deaths of two American soldiers and a civilian interpreter in the Palmyra area.
The U.N. says IS still boasts between 5,000 and 7,000 fighters in Iraq and Syria.
