British Air Force Typhoon FGR4s have conducted a mission with French aircraft in a coordinated attack on an underground arms cache in Syrian territory employed by the IS group, as stated by the UK's MoD.
The location, identified by intelligence, was assessed as containing munitions and bombs, the release indicated, and was located in hills just to the north of Palmyra in Syria's central region.
"The RAF jets employed laser-guided Paveway IV weapons to strike a series of approach shafts down to the facility... preliminary assessments are that the objective was successfully hit," officials stated.
There was no indication of any civilian casualties in the operation conducted Saturday night and all the aircraft returned to base without incident, the defence officials confirmed.
The Typhoon fighters were assisted by a Voyager tanker plane.
Daesh - alternatively referred to as ISIS - imposed militant control over significant areas in both Syria and Iraq before its territorial defeat in 2019.
"This action demonstrates our UK leadership, and resolve to stand shoulder to shoulder with our partners, to eliminate any revival of IS and their violent and radical beliefs in the Middle East," Britain's Defence Chief the Defence Secretary remarked.
British military aircraft have carried out patrols over Syrian airspace to "prevent any attempted resurgence" of Islamic State after its defeat at the climactic battle in Baghuz in 2019, the authorities noted.
"I want to thank every member of British forces participating in this strike for their skill and their courage," Healey added. "They were among a great many British troops stationed over the holidays. This action, to remove militants who threaten our way of life, shows how UK forces are prepared to act, continuously, ensuring Britain's security within its borders and powerful internationally."
In December, the American forces carried out what it termed a "large-scale strike" against IS targets in Syria, after an ambush resulted in the deaths of two American soldiers and a civilian interpreter in the Palmyra area.
The UN reports Islamic State still has between 5,000 and 7,000 fighters in Iraq and Syria.
