Royal Air Force Typhoon FGR4s have operated alongside France's air force in a joint strike targeting an subterranean weapons facility in Syria operated by the Daesh militant organization, according to the UK's MoD.
The location, identified by surveillance, was thought to be containing munitions and bombs, the statement said, and was located in mountainous terrain just to the north of the historic site of Palmyra in Syria's central region.
"The RAF jets used precision-guided Paveway IV munitions to hit a number of approach shafts down to the site... early reports are that the target was engaged successfully," the MoD said.
There was no sign of any harm to civilians in the attack conducted Saturday night and every plane involved returned to base without incident, the defence officials confirmed.
The Typhoon FGR4s were supported by a Voyager refuelling tanker.
Daesh - also known as ISIS - enforced extremist governance over large swathes of Iraq and Syria before its territorial defeat in 2019.
"This action demonstrates the UK's leading role, and resolve to work closely with our allies, to eradicate any re-emergence of the terrorist group and their dangerous and violent ideologies in the area," the British Defence Secretary the Defence Secretary stated.
UK warplanes have performed overwatch operations over Syria to "deter any efforts to regroup" of Islamic State following its routing at the battle of Baghuz in 2019, the authorities noted.
"I must thank all the members of our armed forces participating in this operation for their skill and their bravery," Healey commented. "Including them were thousands of UK service members on duty over the festive period. This mission, to eliminate militants who endanger our safety, highlights how our armed forces are always on standby, throughout the year, keeping Britain secure within its borders and influential overseas."
In December, the American forces executed what it described as a "major assault" on Islamic State objectives in Syria, following an attack resulted in the deaths of two American soldiers and a civilian linguist in the Palmyra area.
The UN reports Daesh still has roughly 5-7 thousand fighters in Syria and Iraq.
