Royal Air Force Typhoon jets have conducted a mission with French aircraft in a combined operation on an subterranean weapons facility in Syria used by the IS group, according to the British defence ministry.
The facility, pinpointed through reconnaissance, was assessed as housing weapons and explosive materials, the announcement noted, and was situated in hills just above the ancient city of Palmyra in the heart of Syria.
"The RAF jets employed Paveway IV guided bombs to hit a several approach shafts down to the facility... initial indications suggest the objective was successfully hit," officials stated.
There was no evidence of any civilian impact in the strike on Saturday evening and each participating jet made a safe return, the defence officials confirmed.
The Typhoon fighters were supported by a Voyager tanker plane.
Daesh - referred to as ISIS - imposed extremist governance over large swathes of Iraq and Syria before its territorial defeat in 2019.
"This strike underscores British leadership, and resolve to operate in unison with allied nations, to eradicate any resurgence of the terrorist group and their violent and radical beliefs in the Middle East," UK Defence Secretary the minister remarked.
British military aircraft have carried out surveillance missions over Syria to "deter any efforts to regroup" of IS subsequent to its military defeat at the Baghuz confrontation in the year 2019, the ministry said.
"I extend gratitude to every member of the UK armed forces involved in this strike for their professionalism and their courage," Healey said. "Including them were numerous British troops on duty over the festive period. This action, to eliminate terrorist threats who pose a risk to our security, highlights how UK forces are always on standby, all year round, protecting the UK domestically and strong abroad."
During December, the United States armed forces carried out what it described as a "massive strike" targeting IS targets in Syria, subsequent to an ambush claimed the lives of two US troops and a civilian interpreter in the Palmyra area.
The United Nations reports IS still boasts between 5,000 and 7,000 fighters in Syria and Iraq.
