Royal Air Force Typhoon jets have operated alongside French warplanes in a combined operation on an subterranean weapons facility in Syria used by the Daesh militant organization, according to the British defence ministry.
The location, pinpointed through reconnaissance, was assessed as containing munitions and bombs, the release indicated, and was positioned in mountains just above the ancient city of Palmyra in Syria's central region.
"The RAF jets used precision-guided Paveway IV munitions to strike a several approach shafts down to the site... early reports indicate the target was engaged successfully," the ministry announced.
There was no sign of any civilian casualties in the operation conducted Saturday night and every plane involved made a safe return, the MoD added.
The Typhoon FGR4s were assisted by a Voyager refuelling tanker.
The Islamic State group - referred to as ISIS - established jihadist rule over large swathes of Syria and Iraq prior to its 2019 collapse.
"This action underscores British leadership, and commitment to work closely with our partners, to eradicate any resurgence of the terrorist group and their violent and radical beliefs in the region," Britain's Defence Chief the minister remarked.
British military aircraft have carried out patrols over Syria to "forestall any efforts to regroup" of IS following its military defeat at the battle of Baghuz in 2019, the ministry said.
"I extend gratitude to the personnel of British forces participating in this mission for their skill and their valour," Healey said. "They were among thousands of British troops on duty over the festive period. This mission, to remove terrorist threats who pose a risk to our way of life, demonstrates how UK forces are always on standby, continuously, ensuring Britain's security domestically and powerful internationally."
