Royal Air Force Typhoon jets have operated alongside France's air force in a joint strike against an subterranean weapons facility in Syria operated by the Daesh militant organization, per a report from the UK Ministry of Defence.
The facility, identified by surveillance, was thought to be storing arms and explosives, the statement said, and was situated in hills just north of the historic site of Palmyra in Syria's central region.
"Our aircraft employed Paveway IV guided bombs to strike a several approach shafts providing entry to the site... initial indications suggest the strike was effective," the ministry announced.
There was no sign of any harm to civilians in the operation late on Saturday and each participating jet returned to base without incident, the ministry further stated.
The Typhoon fighters were backed up by a Voyager aerial refuelling aircraft.
IS - referred to as the so-called Islamic State - imposed jihadist rule over parts of Syria and Iraq until 2019.
"This strike demonstrates the UK's leading role, and resolve to work closely with our allies, to eradicate any revival of Daesh and their dangerous and violent ideologies in the area," UK Defence Secretary the minister said.
British military aircraft have performed surveillance missions over Syria to "prevent any efforts to regroup" of IS following its routing at the climactic battle in Baghuz in the year 2019, the MoD reported.
"I must thank all the members of British forces who took part in this strike for their skill and their bravery," he added. "They were among a great many British personnel on duty over the holidays. This operation, to remove dangerous terrorists who threaten our safety, shows how UK forces are always on standby, throughout the year, ensuring Britain's security within its borders and influential overseas."
During December, the US military executed what it described as a "large-scale strike" on Islamic State objectives in the country, following an ambush claimed the lives of two US troops and a local interpreter in the Palmyra area.
The UN estimates Daesh still has between 5,000 and 7,000 militants in Iraq and Syria.
