British Air Force Typhoon FGR4s have operated alongside France's air force in a coordinated attack on an subterranean weapons facility in Syrian territory used by the IS group, per a report from the UK's MoD.
The facility, located using surveillance, was assessed as storing arms and explosives, the release indicated, and was positioned in mountainous terrain just to the north of Palmyra in Syria's central region.
"The RAF jets employed laser-guided Paveway IV weapons to hit a series of access tunnels down to the depot... initial indications are that the target was engaged successfully," officials stated.
There was no indication of any civilian impact in the attack conducted Saturday night and each participating jet returned to base without incident, the ministry further stated.
The Typhoon FGR4s were backed up by a Voyager tanker plane.
IS - alternatively referred to as the so-called Islamic State - enforced extremist governance over significant areas in both Syria and Iraq until 2019.
"This strike demonstrates British leadership, and determination to work closely with our allies, to stamp out any revival of the terrorist group and their violent and radical beliefs in the region," the British Defence Secretary the Defence Secretary remarked.
British military aircraft have carried out surveillance missions over Syrian airspace to "prevent any attempted resurgence" of Islamic State subsequent to its defeat at the battle of Baghuz in 2019, the MoD reported.
"I want to thank the personnel of British forces participating in this mission for their professionalism and their valour," he added. "They were part of a great many British troops stationed over the festive period. This mission, to eliminate militants who threaten our way of life, demonstrates how British military are always on standby, all year round, protecting the UK domestically and influential overseas."
During December, the United States armed forces conducted what it termed a "major assault" on Islamic State objectives in Syria, following an attack resulted in the deaths of two US servicemembers and a local interpreter in Palmyra.
The U.N. estimates Islamic State still has between 5,000 and 7,000 fighters in Syria and Iraq.
