RAF Typhoon FGR4s have joined forces with French aircraft in a coordinated attack targeting an subterranean weapons facility in Syrian territory employed by the IS group, according to the UK's MoD.
The site, identified by reconnaissance, was thought to be containing munitions and bombs, the announcement noted, and was located in mountains just north of the historic site of Palmyra in the heart of Syria.
"Our fighter planes utilized laser-guided Paveway IV weapons to target a series of entry passages leading to the facility... preliminary assessments indicate the objective was successfully hit," the MoD said.
There was no indication of any civilian impact in the attack late on Saturday and each participating jet returned to base without incident, the MoD added.
The Typhoon FGR4s were assisted by a Voyager refuelling tanker.
Daesh - alternatively referred to as Daesh - enforced militant control over significant areas in Iraq and Syria until 2019.
"This operation demonstrates our UK leadership, and commitment to work closely with our partners, to stamp out any re-emergence of Daesh and their dangerous and violent ideologies in the region," the British Defence Secretary the minister remarked.
British military aircraft have conducted overwatch operations over Syrian airspace to "deter any attempted comeback" of the group subsequent to its defeat at the climactic battle in Baghuz in the year 2019, the authorities noted.
"I want to thank every member of our armed forces involved in this mission for their professionalism and their courage," he said. "They were among numerous UK service members deployed over the holidays. This action, to remove militants who pose a risk to our security, highlights how British military are prepared to act, all year round, keeping Britain secure within its borders and powerful internationally."
In December, the US military carried out what it described as a "major assault" targeting Islamic State objectives in the country, following an ambush claimed the lives of two US troops and a local interpreter in the Palmyra area.
The UN says Daesh still maintains roughly 5-7 thousand fighters in Iraq and Syria.
