Royal Air Force Typhoon fighter aircraft have operated alongside French warplanes in a coordinated attack on an underground arms cache in Syria operated by the IS group, as stated by the UK Ministry of Defence.
The facility, pinpointed through surveillance, was assessed as housing weapons and explosive materials, the statement said, and was located in mountainous terrain just to the north of the historic site of Palmyra in central Syria.
"The RAF jets employed precision-guided Paveway IV munitions to hit a several approach shafts down to the depot... preliminary assessments indicate the target was engaged successfully," the ministry announced.
There was no evidence of any civilian casualties in the strike on Saturday evening and each participating jet made a safe return, the defence officials confirmed.
The Typhoon FGR4s were backed up by a Voyager aerial refuelling aircraft.
Daesh - referred to as the so-called Islamic State - enforced militant control over parts of Syria and Iraq before its territorial defeat in 2019.
"This action underscores British leadership, and commitment to operate in unison with our partners, to eliminate any re-emergence of the terrorist group and their violent and radical beliefs in the region," Britain's Defence Chief the Defence Secretary said.
RAF aircraft have conducted surveillance missions over Syrian airspace to "deter any attempted comeback" of Islamic State after its defeat at the Baghuz confrontation in the year 2019, the authorities noted.
"I extend gratitude to every member of our armed forces participating in this strike for their expertise and their valour," Healey said. "They were part of numerous British troops stationed over the festive period. This operation, to take out dangerous terrorists who threaten our security, shows how UK forces are prepared to act, continuously, keeping Britain secure domestically and strong abroad."
During December, the American forces executed what it termed a "major assault" targeting Daesh sites in Syria, subsequent to an ambush resulted in the deaths of two US troops and a civilian linguist in the Palmyra area.
The United Nations reports IS still has between 5,000 and 7,000 combatants in both countries.
