RAF Typhoon fighter aircraft have conducted a mission with French aircraft in a combined operation on an subterranean weapons facility in Syria used by the IS group, as stated by the UK Ministry of Defence.
The location, located using reconnaissance, was believed to be storing arms and explosives, the release indicated, and was located in mountainous terrain just above the ancient city of Palmyra in Syria's central region.
"Our fighter planes utilized laser-guided Paveway IV weapons to hit a number of approach shafts down to the site... initial indications suggest the strike was effective," officials stated.
There was no indication of any civilian casualties in the strike on Saturday evening and every plane involved returned safely, the defence officials confirmed.
The British jets were assisted by a Voyager refuelling tanker.
IS - alternatively referred to as ISIS - imposed militant control over parts of Syria and Iraq prior to its 2019 collapse.
"This action demonstrates British leadership, and resolve to work closely with allied nations, to eliminate any resurgence of Daesh and their harmful and extremist ideologies in the region," UK Defence Secretary the Defence Secretary remarked.
British military aircraft have performed overwatch operations over Syria to "forestall any attempted comeback" of IS after its military defeat at the Baghuz confrontation in 2019, the MoD reported.
"I want to thank the personnel of the UK armed forces who took part in this strike for their expertise and their bravery," he added. "They were part of thousands of British personnel on duty over the festive period. This operation, to take out militants who threaten our safety, demonstrates how UK forces are prepared to act, throughout the year, keeping Britain secure within its borders and influential overseas."
During December, the American forces executed what it termed a "massive strike" targeting IS targets in the country, following an attack resulted in the deaths of two US troops and a civilian interpreter in Palmyra.
The UN says Daesh still maintains an estimated 5,000 to 7,000 militants in Iraq and Syria.
