British Air Force Typhoon fighter aircraft have operated alongside French aircraft in a combined operation against an underground arms cache in Syrian territory used by the Daesh militant organization, according to the British defence ministry.
The location, identified by intelligence, was thought to be storing arms and explosives, the announcement noted, and was located in mountainous terrain just north of the ancient city of Palmyra in Syria's central region.
"Our fighter planes used precision-guided Paveway IV munitions to strike a number of access tunnels down to the facility... initial indications are that the strike was effective," officials stated.
There was no indication of any harm to civilians in the strike conducted Saturday night and each participating jet returned safely, the defence officials confirmed.
The Typhoon FGR4s were assisted by a Voyager aerial refuelling aircraft.
The Islamic State group - referred to as ISIS - enforced extremist governance over large swathes of Iraq and Syria until 2019.
"This operation underscores the UK's leading role, and resolve to work closely with our allies, to stamp out any resurgence of IS and their violent and radical beliefs in the region," Britain's Defence Chief the Defence Secretary said.
UK warplanes have carried out surveillance missions over Syrian airspace to "deter any attempted comeback" of the group subsequent to its routing at the climactic battle in Baghuz in 2019, the ministry said.
"I want to thank the personnel of the UK armed forces who took part in this mission for their skill and their valour," the Defence Secretary said. "They were part of a great many British personnel stationed over Christmas and New Year. This operation, to take out terrorist threats who threaten our way of life, demonstrates how UK forces are prepared to act, throughout the year, ensuring Britain's security at home and strong abroad."
Last December, the United States armed forces executed what it described as a "large-scale strike" against Islamic State objectives in Syria, following an attack resulted in the deaths of two American soldiers and a civilian interpreter in Palmyra.
The United Nations says Islamic State still boasts between 5,000 and 7,000 militants in Syria and Iraq.
