RAF Typhoon jets have operated alongside French aircraft in a combined operation on an subterranean weapons facility in Syrian territory used by the Daesh militant organization, according to the UK's MoD.
The location, identified by surveillance, was thought to be storing arms and explosives, the release indicated, and was located in mountains just to the north of Palmyra in central Syria.
"The RAF jets utilized precision-guided Paveway IV munitions to target a several approach shafts leading to the depot... early reports indicate the strike was effective," officials stated.
There was no indication of any harm to civilians in the operation conducted Saturday night and all the aircraft returned safely, the defence officials confirmed.
The Typhoon fighters were assisted by a Voyager refuelling tanker.
Daesh - referred to as ISIS - established jihadist rule over significant areas in both Syria and Iraq until 2019.
"This action underscores British leadership, and determination to stand shoulder to shoulder with our partners, to eliminate any resurgence of the terrorist group and their violent and radical beliefs in the Middle East," the British Defence Secretary the minister stated.
British military aircraft have conducted surveillance missions over Syria to "deter any attempted resurgence" of Islamic State following its defeat at the climactic battle in Baghuz in the year 2019, the MoD reported.
"I extend gratitude to all the members of British forces involved in this strike for their professionalism and their courage," the Defence Secretary added. "They were among thousands of UK service members deployed over Christmas and New Year. This mission, to remove militants who pose a risk to our safety, shows how British military are prepared to act, throughout the year, protecting the UK at home and powerful internationally."
In December, the US military executed what it described as a "massive strike" on Daesh sites in Syria, subsequent to an attack killed two US troops and a civilian interpreter in the Palmyra area.
The U.N. reports Daesh still boasts roughly 5-7 thousand fighters in Iraq and Syria.
