Royal Air Force Typhoon fighter aircraft have operated alongside French aircraft in a combined operation on an subterranean weapons facility in Syrian territory employed by the IS group, as stated by the UK's MoD.
The site, pinpointed through surveillance, was believed to be containing munitions and bombs, the statement said, and was located in hills just north of the ancient city of Palmyra in central Syria.
"The RAF jets utilized Paveway IV guided bombs to hit a several approach shafts down to the site... preliminary assessments indicate the objective was successfully hit," officials stated.
There was no indication of any civilian casualties in the strike conducted Saturday night and each participating jet returned to base without incident, the ministry further stated.
The Typhoon FGR4s were assisted by a Voyager aerial refuelling aircraft.
IS - referred to as the so-called Islamic State - enforced militant control over parts of Iraq and Syria until 2019.
"This operation shows the UK's leading role, and determination to stand shoulder to shoulder with our allies, to stamp out any resurgence of IS and their harmful and extremist ideologies in the region," the British Defence Secretary the Defence Secretary remarked.
British military aircraft have conducted overwatch operations over Syria to "prevent any efforts to regroup" of Islamic State following its routing at the battle of Baghuz in the year 2019, the authorities noted.
"I extend gratitude to all the members of our armed forces involved in this operation for their skill and their courage," the Defence Secretary said. "They were among a great many British personnel deployed over the holidays. This mission, to remove militants who pose a risk to our security, highlights how our armed forces are ready to step up, throughout the year, ensuring Britain's security at home and influential overseas."
During December, the United States armed forces executed what it termed a "large-scale strike" on Islamic State objectives in Syria, subsequent to an attack resulted in the deaths of two US servicemembers and a civilian interpreter in Palmyra.
The UN says IS still has between 5,000 and 7,000 militants in both countries.
