Royal Air Force Typhoon fighter aircraft have conducted a mission with France's air force in a combined operation targeting an hidden munitions depot in Syrian territory used by the Islamic State group (IS), according to the UK Ministry of Defence.
The site, identified by surveillance, was assessed as containing munitions and bombs, the statement said, and was situated in mountains just to the north of the ancient city of Palmyra in the heart of Syria.
"The RAF jets employed precision-guided Paveway IV munitions to strike a number of approach shafts leading to the facility... preliminary assessments suggest the strike was effective," the ministry announced.
There was no indication of any civilian casualties in the attack conducted Saturday night and all the aircraft returned to base without incident, the ministry further stated.
The British jets were backed up by a Voyager tanker plane.
The Islamic State group - alternatively referred to as the so-called Islamic State - enforced militant control over parts of Syria and Iraq before its territorial defeat in 2019.
"This strike demonstrates the UK's leading role, and commitment to stand shoulder to shoulder with our partners, to stamp out any revival of the terrorist group and their violent and radical beliefs in the Middle East," the British Defence Secretary the minister remarked.
UK warplanes have conducted surveillance missions over Syria to "prevent any attempted comeback" of the group subsequent to its defeat at the climactic battle in Baghuz in the year 2019, the MoD reported.
"I want to thank every member of our armed forces involved in this strike for their skill and their bravery," Healey said. "Including them were numerous UK service members deployed over the holidays. This operation, to take out militants who endanger our safety, highlights how UK forces are ready to step up, continuously, protecting the UK at home and powerful internationally."
During December, the US military executed what it called a "massive strike" against Daesh sites in the country, after an ambush killed two American soldiers and a civilian linguist in Palmyra.
The United Nations estimates IS still boasts roughly 5-7 thousand militants in Iraq and Syria.
