RAF Typhoon fighter aircraft have conducted a mission with French aircraft in a combined operation on an hidden munitions depot in Syria operated by the IS group, as stated by the UK's MoD.
The site, identified by reconnaissance, was thought to be containing munitions and bombs, the announcement noted, and was situated in mountainous terrain just above the historic site of Palmyra in Syria's central region.
"Our aircraft employed precision-guided Paveway IV munitions to strike a several approach shafts providing entry to the depot... initial indications are that the target was engaged successfully," the MoD said.
There was no sign of any harm to civilians in the attack late on Saturday and all the aircraft made a safe return, the defence officials confirmed.
The Typhoon fighters were assisted by a Voyager refuelling tanker.
Daesh - referred to as ISIS - enforced extremist governance over large swathes of both Syria and Iraq prior to its 2019 collapse.
"This operation shows British leadership, and determination to operate in unison with our allies, to eliminate any revival of Daesh and their violent and radical beliefs in the Middle East," the British Defence Secretary the Defence Secretary said.
RAF aircraft have performed patrols over Syria to "deter any efforts to regroup" of IS following its defeat at the Baghuz confrontation in 2019, the MoD reported.
"I extend gratitude to the personnel of our armed forces participating in this strike for their skill and their valour," the Defence Secretary commented. "They were part of numerous UK service members on duty over Christmas and New Year. This operation, to remove terrorist threats who pose a risk to our safety, demonstrates how British military are always on standby, throughout the year, ensuring Britain's security within its borders and strong abroad."
Last December, the United States armed forces conducted what it termed a "major assault" against Islamic State objectives in Syria, subsequent to an assault resulted in the deaths of two US troops and a civilian interpreter in Palmyra.
The UN reports Islamic State still has an estimated 5,000 to 7,000 combatants in Syria and Iraq.
