Royal Air Force Typhoon jets have operated alongside French aircraft in a joint strike against an underground arms cache in Syria used by the Daesh militant organization, as stated by the UK's MoD.
The location, pinpointed through reconnaissance, was thought to be storing arms and explosives, the announcement noted, and was located in mountains just north of the historic site of Palmyra in the heart of Syria.
"The RAF jets utilized Paveway IV guided bombs to hit a number of access tunnels leading to the depot... preliminary assessments suggest the objective was successfully hit," the MoD said.
There was no evidence of any civilian impact in the operation late on Saturday and every plane involved made a safe return, the ministry further stated.
The British jets were backed up by a Voyager tanker plane.
The Islamic State group - also known as the so-called Islamic State - enforced militant control over significant areas in Iraq and Syria prior to its 2019 collapse.
"This action shows our UK leadership, and resolve to stand shoulder to shoulder with our partners, to eliminate any revival of the terrorist group and their harmful and extremist ideologies in the area," the British Defence Secretary John Healey remarked.
British military aircraft have conducted surveillance missions over Syrian airspace to "deter any attempted resurgence" of the group after its military defeat at the climactic battle in Baghuz in the year 2019, the MoD reported.
"I must thank the personnel of our armed forces participating in this strike for their professionalism and their courage," the Defence Secretary added. "They were part of thousands of UK service members deployed over the festive period. This mission, to remove terrorist threats who threaten our safety, shows how UK forces are always on standby, continuously, protecting the UK domestically and strong abroad."
In December, the US military carried out what it called a "massive strike" on Islamic State objectives in the country, after an assault resulted in the deaths of two US troops and a civilian linguist in the Palmyra area.
The United Nations reports Islamic State still maintains between 5,000 and 7,000 combatants in both countries.
