British Air Force Typhoon FGR4s have conducted a mission with French aircraft in a combined operation targeting an underground arms cache in Syria employed by the Daesh militant organization, per a report from the UK's MoD.
The site, identified by intelligence, was thought to be storing arms and explosives, the announcement noted, and was located in hills just above the ancient city of Palmyra in central Syria.
"Our aircraft utilized laser-guided Paveway IV weapons to hit a series of entry passages leading to the facility... initial indications are that the target was engaged successfully," the ministry announced.
There was no evidence of any harm to civilians in the attack on Saturday evening and all the aircraft made a safe return, the defence officials confirmed.
The British jets were supported by a Voyager refuelling tanker.
The Islamic State group - also known as the so-called Islamic State - established extremist governance over significant areas in both Syria and Iraq prior to its 2019 collapse.
"This strike shows our UK leadership, and commitment to work closely with allied nations, to eliminate any resurgence of IS and their harmful and extremist ideologies in the area," UK Defence Secretary John Healey remarked.
RAF aircraft have carried out overwatch operations over Syria to "prevent any attempted resurgence" of IS following its military defeat at the climactic battle in Baghuz in 2019, the authorities noted.
"I want to thank the personnel of British forces participating in this strike for their skill and their courage," the Defence Secretary added. "They were part of a great many British personnel deployed over the holidays. This action, to remove terrorist threats who threaten our safety, highlights how our armed forces are always on standby, all year round, ensuring Britain's security domestically and powerful internationally."
In December, the US military carried out what it described as a "large-scale strike" targeting Daesh sites in Syria, subsequent to an attack resulted in the deaths of two American soldiers and a civilian interpreter in Palmyra.
The United Nations reports Islamic State still has roughly 5-7 thousand combatants in Syria and Iraq.
