Royal Air Force Typhoon FGR4s have joined forces with French aircraft in a joint strike targeting an subterranean weapons facility in Syrian territory employed by the Daesh militant organization, according to the British defence ministry.
The location, located using intelligence, was thought to be storing arms and explosives, the statement said, and was situated in hills just north of Palmyra in the heart of Syria.
"Our aircraft used Paveway IV guided bombs to hit a series of approach shafts leading to the depot... initial indications indicate the strike was effective," the ministry announced.
There was no sign of any civilian casualties in the operation on Saturday evening and all the aircraft returned to base without incident, the MoD added.
The Typhoon fighters were assisted by a Voyager aerial refuelling aircraft.
The Islamic State group - also known as Daesh - established extremist governance over large swathes of Syria and Iraq prior to its 2019 collapse.
"This action demonstrates British leadership, and resolve to work closely with our partners, to eradicate any resurgence of the terrorist group and their dangerous and violent ideologies in the region," UK Defence Secretary the Defence Secretary said.
British military aircraft have performed overwatch operations over Syria to "prevent any efforts to regroup" of IS subsequent to its routing at the Baghuz confrontation in the year 2019, the authorities noted.
"I extend gratitude to every member of the UK armed forces involved in this operation for their skill and their bravery," he said. "Including them were numerous British personnel on duty over the festive period. This action, to eliminate terrorist threats who endanger our safety, shows how UK forces are prepared to act, throughout the year, ensuring Britain's security at home and influential overseas."
In December, the United States armed forces carried out what it termed a "massive strike" on Daesh sites in the country, subsequent to an attack resulted in the deaths of two US servicemembers and a civilian interpreter in Palmyra.
The United Nations says Islamic State still boasts between 5,000 and 7,000 fighters in both countries.
