Royal Air Force Typhoon FGR4s have operated alongside French aircraft in a coordinated attack against an hidden munitions depot in Syrian territory operated by the Daesh militant organization, as stated by the British defence ministry.
The facility, located using surveillance, was thought to be housing weapons and explosive materials, the statement said, and was positioned in mountains just to the north of Palmyra in Syria's central region.
"The RAF jets utilized Paveway IV guided bombs to hit a series of access tunnels down to the site... initial indications suggest the objective was successfully hit," the MoD said.
There was no evidence of any civilian casualties in the strike on Saturday evening and every plane involved returned to base without incident, the MoD added.
The Typhoon fighters were backed up by a Voyager aerial refuelling aircraft.
IS - also known as ISIS - established militant control over large swathes of Iraq and Syria prior to its 2019 collapse.
"This operation underscores the UK's leading role, and determination to operate in unison with our partners, to eradicate any re-emergence of Daesh and their dangerous and violent ideologies in the region," UK Defence Secretary John Healey remarked.
British military aircraft have carried out surveillance missions over Syria to "forestall any attempted comeback" of Islamic State subsequent to its routing at the climactic battle in Baghuz in 2019, the MoD reported.
"I want to thank all the members of the UK armed forces involved in this strike for their professionalism and their valour," Healey added. "They were part of numerous British personnel deployed over the festive period. This action, to eliminate militants who endanger our safety, highlights how UK forces are ready to step up, all year round, keeping Britain secure within its borders and strong abroad."
During December, the United States armed forces carried out what it described as a "massive strike" against IS targets in Syria, subsequent to an attack claimed the lives of two US troops and a civilian interpreter in Palmyra.
The United Nations estimates IS still maintains an estimated 5,000 to 7,000 militants in Syria and Iraq.
