British Air Force Typhoon FGR4s have operated alongside France's air force in a coordinated attack targeting an subterranean weapons facility in Syria used by the IS group, according to the UK's MoD.
The facility, identified by surveillance, was assessed as storing arms and explosives, the announcement noted, and was positioned in mountainous terrain just to the north of Palmyra in central Syria.
"Our fighter planes employed laser-guided Paveway IV weapons to strike a number of entry passages providing entry to the facility... early reports suggest the objective was successfully hit," officials stated.
There was no sign of any civilian impact in the operation conducted Saturday night and all the aircraft made a safe return, the ministry further stated.
The Typhoon FGR4s were supported by a Voyager refuelling tanker.
IS - also known as the so-called Islamic State - imposed jihadist rule over parts of both Syria and Iraq until 2019.
"This operation shows British leadership, and commitment to work closely with our allies, to eradicate any re-emergence of IS and their violent and radical beliefs in the region," UK Defence Secretary the Defence Secretary remarked.
British military aircraft have conducted overwatch operations over Syria to "forestall any attempted comeback" of IS subsequent to its defeat at the Baghuz confrontation in 2019, the authorities noted.
"I extend gratitude to every member of our armed forces who took part in this operation for their professionalism and their valour," the Defence Secretary commented. "They were part of numerous British personnel stationed over the holidays. This mission, to remove terrorist threats who threaten our way of life, demonstrates how British military are prepared to act, throughout the year, protecting the UK domestically and influential overseas."
In December, the US military carried out what it described as a "large-scale strike" targeting IS targets in the country, after an ambush claimed the lives of two US servicemembers and a civilian interpreter in Palmyra.
The United Nations reports Daesh still has roughly 5-7 thousand combatants in Syria and Iraq.
