British Air Force Typhoon jets have joined forces with French aircraft in a coordinated attack on an subterranean weapons facility in Syrian territory employed by the Daesh militant organization, per a report from the British defence ministry.
The location, identified by reconnaissance, was thought to be containing munitions and bombs, the release indicated, and was positioned in mountainous terrain just north of Palmyra in central Syria.
"The RAF jets utilized Paveway IV guided bombs to hit a several entry passages leading to the site... initial indications suggest the objective was successfully hit," the MoD said.
There was no sign of any harm to civilians in the strike conducted Saturday night and each participating jet made a safe return, the MoD added.
The Typhoon fighters were assisted by a Voyager aerial refuelling aircraft.
Daesh - also known as ISIS - established militant control over significant areas in Syria and Iraq until 2019.
"This operation demonstrates the UK's leading role, and commitment to operate in unison with allied nations, to stamp out any re-emergence of IS and their dangerous and violent ideologies in the area," UK Defence Secretary the minister said.
UK warplanes have carried out surveillance missions over Syrian airspace to "deter any efforts to regroup" of Islamic State following its defeat at the Baghuz confrontation in 2019, the MoD reported.
"I want to thank all the members of the UK armed forces involved in this strike for their skill and their courage," he said. "Including them were thousands of British personnel on duty over the festive period. This operation, to remove terrorist threats who endanger our way of life, demonstrates how UK forces are prepared to act, continuously, ensuring Britain's security at home and influential overseas."
In December, the American forces executed what it called a "major assault" targeting Daesh sites in Syria, subsequent to an ambush killed two US servicemembers and a civilian interpreter in Palmyra.
The U.N. estimates IS still boasts between 5,000 and 7,000 militants in Syria and Iraq.
