RAF Typhoon fighter aircraft have joined forces with French aircraft in a combined operation against an subterranean weapons facility in Syrian territory operated by the Daesh militant organization, as stated by the UK's MoD.
The location, pinpointed through surveillance, was thought to be containing munitions and bombs, the announcement noted, and was situated in mountainous terrain just above the historic site of Palmyra in central Syria.
"Our aircraft utilized Paveway IV guided bombs to hit a number of approach shafts providing entry to the depot... initial indications are that the target was engaged successfully," the MoD said.
There was no indication of any harm to civilians in the attack conducted Saturday night and all the aircraft returned safely, the defence officials confirmed.
The British jets were backed up by a Voyager tanker plane.
Daesh - alternatively referred to as Daesh - established jihadist rule over parts of both Syria and Iraq prior to its 2019 collapse.
"This strike demonstrates our UK leadership, and determination to stand shoulder to shoulder with our partners, to eliminate any re-emergence of IS and their dangerous and violent ideologies in the Middle East," the British Defence Secretary John Healey said.
UK warplanes have conducted overwatch operations over Syrian airspace to "deter any attempted resurgence" of IS subsequent to its military defeat at the climactic battle in Baghuz in 2019, the MoD reported.
"I extend gratitude to every member of British forces participating in this mission for their professionalism and their valour," he added. "They were part of numerous British personnel on duty over the holidays. This mission, to remove dangerous terrorists who threaten our security, highlights how UK forces are prepared to act, continuously, protecting the UK within its borders and powerful internationally."
During December, the US military executed what it called a "major assault" targeting Islamic State objectives in Syria, after an ambush resulted in the deaths of two US troops and a civilian interpreter in the Palmyra area.
The UN says Daesh still boasts roughly 5-7 thousand militants in both countries.
