RAF Typhoon jets have joined forces with France's air force in a coordinated attack on an underground arms cache in Syrian territory operated by the Daesh militant organization, per a report from the UK's MoD.
The location, pinpointed through intelligence, was believed to be storing arms and explosives, the statement said, and was located in hills just above the historic site of Palmyra in central Syria.
"Our fighter planes employed precision-guided Paveway IV munitions to strike a series of approach shafts providing entry to the facility... early reports suggest the target was engaged successfully," the MoD said.
There was no evidence of any harm to civilians in the operation conducted Saturday night and every plane involved returned to base without incident, the MoD added.
The Typhoon fighters were backed up by a Voyager aerial refuelling aircraft.
Daesh - also known as Daesh - established jihadist rule over significant areas in Syria and Iraq before its territorial defeat in 2019.
"This operation underscores British leadership, and commitment to operate in unison with our partners, to stamp out any resurgence of Daesh and their violent and radical beliefs in the area," the British Defence Secretary the Defence Secretary remarked.
British military aircraft have conducted surveillance missions over Syrian airspace to "prevent any efforts to regroup" of IS following its routing at the climactic battle in Baghuz in 2019, the authorities noted.
"I must thank every member of British forces participating in this strike for their expertise and their valour," he said. "They were among a great many UK service members on duty over the festive period. This operation, to remove terrorist threats who pose a risk to our security, shows how British military are ready to step up, all year round, keeping Britain secure at home and influential overseas."
In December, the American forces executed what it described as a "major assault" against Daesh sites in Syria, subsequent to an ambush resulted in the deaths of two US troops and a local interpreter in Palmyra.
The U.N. reports Daesh still maintains between 5,000 and 7,000 fighters in Syria and Iraq.
