Royal Air Force Typhoon fighter aircraft have conducted a mission with France's air force in a joint strike against an underground arms cache in Syrian territory operated by the IS group, according to the British defence ministry.
The location, located using reconnaissance, was assessed as storing arms and explosives, the release indicated, and was located in mountainous terrain just above the ancient city of Palmyra in central Syria.
"The RAF jets utilized precision-guided Paveway IV munitions to target a series of access tunnels providing entry to the depot... 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 all the aircraft returned safely, the MoD added.
The Typhoon fighters were assisted by a Voyager aerial refuelling aircraft.
Daesh - also known as Daesh - enforced jihadist rule over significant areas in Syria and Iraq prior to its 2019 collapse.
"This action underscores the UK's leading role, and resolve to work closely with our partners, to stamp out any re-emergence of the terrorist group and their harmful and extremist ideologies in the region," Britain's Defence Chief the Defence Secretary remarked.
UK warplanes have carried out surveillance missions over Syria to "prevent any efforts to regroup" of Islamic State after its military defeat at the climactic battle in Baghuz in 2019, the ministry said.
"I want to thank all the members of our armed forces who took part in this mission for their skill and their valour," the Defence Secretary added. "They were among a great many British personnel on duty over Christmas and New Year. This action, to eliminate militants who endanger our way of life, demonstrates how UK forces are always on standby, continuously, keeping Britain secure domestically and powerful internationally."
During December, the United States armed forces executed what it termed a "large-scale strike" against Daesh sites in Syria, after an assault claimed the lives of two US servicemembers and a local interpreter in Palmyra.
The United Nations reports IS still maintains an estimated 5,000 to 7,000 combatants in Iraq and Syria.
