Royal Air Force Typhoon FGR4s have joined forces with French aircraft in a combined operation on an subterranean weapons facility in Syrian territory employed by the Daesh militant organization, as stated by the British defence ministry.
The location, located using intelligence, was assessed as storing arms and explosives, the announcement noted, and was located in mountains just north of the historic site of Palmyra in Syria's central region.
"Our aircraft employed Paveway IV guided bombs to hit a several access tunnels providing entry to the site... early reports indicate the target was engaged successfully," officials stated.
There was no indication of any civilian impact in the attack late on Saturday and each participating jet returned to base without incident, the ministry further stated.
The Typhoon FGR4s were assisted by a Voyager tanker plane.
The Islamic State group - referred to as Daesh - imposed extremist governance over large swathes of both Syria and Iraq prior to its 2019 collapse.
"This action shows the UK's leading role, and commitment to work closely with our allies, to eradicate any revival of IS and their dangerous and violent ideologies in the area," Britain's Defence Chief John Healey stated.
British military aircraft have performed surveillance missions over Syria to "forestall any attempted resurgence" of IS following its military defeat at the climactic battle in Baghuz in 2019, the MoD reported.
"I must thank the personnel of British forces participating in this mission for their skill and their valour," the Defence Secretary commented. "They were among numerous UK service members on duty over the festive period. This operation, to take out terrorist threats who pose a risk to our safety, highlights how our armed forces are ready to step up, all year round, protecting the UK domestically and powerful internationally."
In December, the American forces conducted what it described as a "large-scale strike" against Islamic State objectives in the country, subsequent to an attack killed two US servicemembers and a civilian linguist in the Palmyra area.
The UN says Islamic State still maintains between 5,000 and 7,000 militants in both countries.
