Royal Air Force Typhoon fighter aircraft have operated alongside France's air force in a combined operation against an subterranean weapons facility in Syrian territory employed by the Islamic State group (IS), as stated by the British defence ministry.
The site, pinpointed through surveillance, was thought to be storing arms and explosives, the announcement noted, and was located in hills just above Palmyra in the heart of Syria.
"Our aircraft used precision-guided Paveway IV munitions to strike a series of entry passages down to the site... early reports are that the strike was effective," officials stated.
There was no indication of any civilian impact in the operation conducted Saturday night and each participating jet returned to base without incident, the MoD added.
The British jets were assisted by a Voyager aerial refuelling aircraft.
IS - referred to as Daesh - enforced extremist governance over large swathes of both Syria and Iraq until 2019.
"This strike demonstrates our UK leadership, and resolve to work closely with allied nations, to eradicate any revival of Daesh and their dangerous and violent ideologies in the area," UK Defence Secretary the minister remarked.
UK warplanes have carried out overwatch operations over Syrian airspace to "prevent any attempted resurgence" of the group following its routing at the climactic battle in Baghuz in 2019, the ministry said.
"I must thank every member of British forces who took part in this strike for their skill and their courage," the Defence Secretary said. "They were among a great many British troops stationed over Christmas and New Year. This mission, to remove militants who endanger our way of life, shows how our armed forces are ready to step up, continuously, protecting the UK within its borders and influential overseas."
Last December, the United States armed forces carried out what it called a "large-scale strike" against IS targets in Syria, following an ambush resulted in the deaths of two US troops and a civilian interpreter in Palmyra.
The United Nations says Daesh still maintains between 5,000 and 7,000 fighters in Syria and Iraq.
