Royal Air Force Typhoon fighter aircraft have operated alongside French warplanes in a joint strike targeting an underground arms cache in Syria used by the IS group, per a report from the UK's MoD.
The location, located using surveillance, was believed to be storing arms and explosives, the statement said, and was located in mountains just to the north of the historic site of Palmyra in Syria's central region.
"Our fighter planes utilized laser-guided Paveway IV weapons to target a number of approach shafts leading to the depot... early reports indicate the objective was successfully hit," the MoD said.
There was no evidence of any civilian impact in the attack on Saturday evening and every plane involved returned safely, the ministry further stated.
The Typhoon fighters were assisted by a Voyager refuelling tanker.
The Islamic State group - referred to as Daesh - enforced jihadist rule over parts of Iraq and Syria until 2019.
"This action shows our UK leadership, and determination to stand shoulder to shoulder with our partners, to eliminate any re-emergence of Daesh and their harmful and extremist ideologies in the Middle East," the British Defence Secretary the minister said.
UK warplanes have carried out patrols over Syria to "prevent any efforts to regroup" of the group following its military defeat at the Baghuz confrontation in the year 2019, the authorities noted.
"I must thank all the members of the UK armed forces involved in this operation for their skill and their valour," he commented. "They were part of numerous British troops deployed over the holidays. This mission, to remove dangerous terrorists who threaten our safety, shows how UK forces are ready to step up, continuously, keeping Britain secure at home and strong abroad."
In December, the American forces executed what it described as a "large-scale strike" targeting Daesh sites in the country, after an attack killed two US servicemembers and a civilian linguist in the Palmyra area.
The United Nations estimates Daesh still maintains an estimated 5,000 to 7,000 fighters in Syria and Iraq.
