British Air Force Typhoon FGR4s have conducted a mission with French aircraft in a joint strike on an subterranean weapons facility in Syrian territory employed by the Daesh militant organization, as stated by the British defence ministry.
The facility, located using reconnaissance, was assessed as containing munitions and bombs, the announcement noted, and was located in mountainous terrain just to the north of the historic site of Palmyra in Syria's central region.
"Our fighter planes used precision-guided Paveway IV munitions to target a several entry passages leading to the site... initial indications suggest the strike was effective," the MoD said.
There was no indication of any harm to civilians in the attack late on Saturday and all the aircraft returned safely, the ministry further stated.
The Typhoon fighters were supported by a Voyager tanker plane.
The Islamic State group - referred to as the so-called Islamic State - imposed jihadist rule over parts of Syria and Iraq before its territorial defeat in 2019.
"This strike shows British leadership, and determination to operate in unison with allied nations, to stamp out any resurgence of IS and their violent and radical beliefs in the region," UK Defence Secretary the minister stated.
British military aircraft have carried out overwatch operations over Syria to "forestall any attempted comeback" of IS subsequent to its military defeat at the Baghuz confrontation in 2019, the MoD reported.
"I must thank every member of the UK armed forces participating in this mission for their expertise and their valour," the Defence Secretary added. "Including them were numerous British troops stationed over the holidays. This operation, to eliminate militants who threaten our safety, demonstrates how UK forces are always on standby, throughout the year, keeping Britain secure at home and influential overseas."
During December, the United States armed forces executed what it termed a "large-scale strike" against Islamic State objectives in the country, following an ambush claimed the lives of two US servicemembers and a civilian linguist in Palmyra.
The United Nations estimates Islamic State still has roughly 5-7 thousand militants in Syria and Iraq.
