Royal Air Force Typhoon jets have joined forces with France's air force in a combined operation on an underground arms cache in Syria employed by the Daesh militant organization, as stated by the UK's MoD.
The facility, located using surveillance, was assessed as housing weapons and explosive materials, the statement said, and was located in mountainous terrain just to the 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 providing entry to the facility... early reports indicate the objective was successfully hit," the MoD said.
There was no evidence of any civilian impact in the strike late on Saturday and each participating jet returned safely, the defence officials confirmed.
The Typhoon fighters were backed up by a Voyager aerial refuelling aircraft.
IS - also known as the so-called Islamic State - established militant control over parts of Iraq and Syria prior to its 2019 collapse.
"This action demonstrates British leadership, and commitment to work closely with allied nations, to eradicate any revival of IS and their violent and radical beliefs in the area," the British Defence Secretary the minister remarked.
British military aircraft have carried out patrols over Syrian airspace to "prevent any attempted comeback" of Islamic State following its military defeat at the Baghuz confrontation in 2019, the ministry said.
"I must thank every member of our armed forces who took part in this operation for their professionalism and their courage," Healey said. "They were part of numerous UK service members on duty over the festive period. This action, to remove dangerous terrorists who pose a risk to our way of life, demonstrates how British military are prepared to act, continuously, protecting the UK at home and influential overseas."
Last December, the US military carried out what it called a "large-scale strike" targeting Daesh sites in Syria, subsequent to an attack killed two US troops and a local interpreter in Palmyra.
The United Nations says Daesh still boasts roughly 5-7 thousand fighters in both countries.
