British Air Force Typhoon jets have operated alongside French aircraft in a coordinated attack on an underground arms cache in Syrian territory employed by the Daesh militant organization, as stated by the British defence ministry.
The location, identified by surveillance, was thought to be containing munitions and bombs, the announcement noted, and was positioned in hills just above the historic site of Palmyra in the heart of Syria.
"Our aircraft utilized Paveway IV guided bombs to strike a number of entry passages providing entry to the facility... preliminary assessments are that the objective was successfully hit," the MoD said.
There was no evidence of any civilian impact in the operation late on Saturday and each participating jet returned safely, the MoD added.
The Typhoon fighters were supported by a Voyager aerial refuelling aircraft.
IS - referred to as Daesh - enforced militant control over large swathes of Syria and Iraq until 2019.
"This action shows British leadership, and resolve to work closely with our partners, to stamp out any revival of the terrorist group and their violent and radical beliefs in the area," the British Defence Secretary the minister stated.
RAF aircraft have performed overwatch operations over Syrian airspace to "deter any efforts to regroup" of the group subsequent to its military defeat at the climactic battle in Baghuz in 2019, the ministry said.
"I must thank all the members of the UK armed forces involved in this strike for their professionalism and their courage," he said. "They were part of numerous British troops on duty over the festive period. This mission, to remove terrorist threats who endanger our way of life, demonstrates how British military are ready to step up, all year round, protecting the UK domestically and influential overseas."
Last December, the US military conducted what it termed a "large-scale strike" on Islamic State objectives in the country, following an assault claimed the lives of two American soldiers and a civilian linguist in the Palmyra area.
The UN says IS still maintains an estimated 5,000 to 7,000 militants in both countries.
