British Air Force Typhoon jets have conducted a mission with France's air force in a joint strike against an hidden munitions depot in Syria operated by the IS group, per a report from the UK's MoD.
The facility, identified by reconnaissance, was believed to be storing arms and explosives, the announcement noted, and was positioned in mountainous terrain just to the north of the historic site of Palmyra in central Syria.
"Our aircraft utilized laser-guided Paveway IV weapons to hit a several approach shafts providing entry to the depot... early reports indicate the objective was successfully hit," officials stated.
There was no evidence of any civilian casualties in the strike on Saturday evening and all the aircraft made a safe return, the defence officials confirmed.
The British jets were supported by a Voyager aerial refuelling aircraft.
IS - referred to as the so-called Islamic State - enforced militant control over large swathes of both Syria and Iraq prior to its 2019 collapse.
"This operation underscores British leadership, and resolve to operate in unison with our partners, to eliminate any re-emergence of Daesh and their violent and radical beliefs in the region," UK Defence Secretary the Defence Secretary remarked.
British military aircraft have performed overwatch operations over Syria to "prevent any attempted comeback" of the group following its military defeat at the Baghuz confrontation in the year 2019, the authorities noted.
"I want to thank all the members of our armed forces participating in this mission for their expertise and their valour," he added. "Including them were numerous British troops on duty over the festive period. This operation, to take out terrorist threats who endanger our safety, demonstrates how British military are always on standby, continuously, ensuring Britain's security at home and strong abroad."
Last December, the American forces executed what it called a "major assault" against Daesh sites in Syria, after an attack claimed the lives of two US servicemembers and a local interpreter in the Palmyra area.
The United Nations estimates IS still boasts roughly 5-7 thousand fighters in Iraq and Syria.
