Royal Air Force Typhoon FGR4s have conducted a mission with France's air force in a coordinated attack targeting an hidden munitions depot in Syrian territory used by the Daesh militant organization, as stated by the UK's MoD.
The facility, located using reconnaissance, was thought to be containing munitions and bombs, the release indicated, and was positioned in mountains just above the historic site of Palmyra in Syria's central region.
"Our aircraft employed Paveway IV guided bombs to target a series of entry passages down to the depot... initial indications indicate the target was engaged successfully," officials stated.
There was no indication of any harm to civilians in the attack late on Saturday and every plane involved made a safe return, the defence officials confirmed.
The Typhoon fighters were backed up by a Voyager tanker plane.
The Islamic State group - alternatively referred to as Daesh - established jihadist rule over significant areas in both Syria and Iraq prior to its 2019 collapse.
"This operation demonstrates our UK leadership, and determination to work closely with allied nations, to eliminate any re-emergence of the terrorist group and their dangerous and violent ideologies in the area," UK Defence Secretary John Healey remarked.
UK warplanes have performed surveillance missions over Syria to "deter any efforts to regroup" of Islamic State after its military defeat at the Baghuz confrontation in 2019, the authorities noted.
"I extend gratitude to every member of the UK armed forces involved in this mission for their professionalism and their bravery," the Defence Secretary commented. "They were among numerous British personnel deployed over the holidays. This action, to eliminate terrorist threats who pose a risk to our security, shows how our armed forces are always on standby, throughout the year, protecting the UK at home and powerful internationally."
During December, the US military carried out what it described as a "massive strike" on IS targets in Syria, subsequent to an attack killed two American soldiers and a civilian interpreter in the Palmyra area.
The UN reports Daesh still has between 5,000 and 7,000 fighters in Syria and Iraq.
