British Air Force Typhoon jets have joined forces with French aircraft in a coordinated attack against an hidden munitions depot in Syria used by the IS group, according to the UK's MoD.
The facility, pinpointed through surveillance, was assessed as containing munitions and bombs, the announcement noted, and was located in mountainous terrain just north of the historic site of Palmyra in the heart of Syria.
"Our fighter planes employed laser-guided Paveway IV weapons to strike a series of access tunnels down to the facility... initial indications are that the objective was successfully hit," the ministry announced.
There was no sign of any civilian impact in the operation on Saturday evening and all the aircraft returned safely, the ministry further stated.
The British jets were backed up by a Voyager tanker plane.
Daesh - referred to as Daesh - enforced jihadist rule over large swathes of Iraq and Syria prior to its 2019 collapse.
"This strike demonstrates our UK leadership, and resolve to operate in unison with allied nations, to eliminate any revival of Daesh and their violent and radical beliefs in the Middle East," the British Defence Secretary John Healey said.
UK warplanes have conducted patrols over Syria to "deter any efforts to regroup" of the group after its routing at the Baghuz confrontation in the year 2019, the MoD reported.
"I want to thank the personnel of our armed forces participating in this mission for their expertise and their courage," Healey said. "Including them were numerous British personnel on duty over Christmas and New Year. This mission, to eliminate terrorist threats who pose a risk to our security, highlights how our armed forces are prepared to act, throughout the year, keeping Britain secure at home and strong abroad."
Last December, the American forces executed what it called a "major assault" targeting IS targets in Syria, following an assault resulted in the deaths of two US servicemembers and a civilian interpreter in Palmyra.
The U.N. reports IS still maintains an estimated 5,000 to 7,000 fighters in both countries.
