British Air Force Typhoon jets have operated alongside French aircraft in a joint strike against an subterranean weapons facility in Syria employed by the IS group, as stated by the British defence ministry.
The location, identified by intelligence, was believed to be storing arms and explosives, the statement said, and was located in hills just to the north of the historic site of Palmyra in central Syria.
"Our aircraft utilized Paveway IV guided bombs to target a several access tunnels leading to the facility... initial indications suggest the target was engaged successfully," the MoD said.
There was no indication of any harm to civilians in the operation conducted Saturday night and each participating jet returned to base without incident, the ministry further stated.
The Typhoon fighters were backed up by a Voyager refuelling tanker.
IS - alternatively referred to as ISIS - established jihadist rule over parts of Iraq and Syria until 2019.
"This action underscores British leadership, and commitment to operate in unison with allied nations, to stamp out any resurgence of the terrorist group and their harmful and extremist ideologies in the area," UK Defence Secretary the minister stated.
British military aircraft have performed surveillance missions over Syrian airspace to "forestall any attempted resurgence" of the group following its defeat at the Baghuz confrontation in 2019, the authorities noted.
"I want to thank every member of our armed forces involved in this strike for their professionalism and their courage," he added. "They were part of a great many British personnel on duty over the festive period. This operation, to take out militants who pose a risk to our security, demonstrates how our armed forces are ready to step up, continuously, ensuring Britain's security at home and strong abroad."
During December, the US military conducted what it described as a "massive strike" targeting Islamic State objectives in the country, after an attack killed two US troops and a local interpreter in the Palmyra area.
The United Nations estimates Islamic State still maintains an estimated 5,000 to 7,000 combatants in Iraq and Syria.
