Royal Air Force Typhoon FGR4s have operated alongside French warplanes in a combined operation on an underground arms cache in Syria used by the Islamic State group (IS), as stated by the UK's MoD.
The facility, pinpointed through surveillance, was believed to be housing weapons and explosive materials, the release indicated, and was situated in hills just above the ancient city of Palmyra in Syria's central region.
"Our aircraft employed precision-guided Paveway IV munitions to strike a several access tunnels down to the site... early reports indicate the objective was successfully hit," the ministry announced.
There was no sign of any civilian casualties in the operation on Saturday evening and every plane involved returned to base without incident, the ministry further stated.
The Typhoon fighters were assisted by a Voyager tanker plane.
Daesh - referred to as the so-called Islamic State - established militant control over parts of Iraq and Syria until 2019.
"This operation demonstrates British leadership, and commitment to stand shoulder to shoulder with allied nations, to eliminate any revival of the terrorist group and their dangerous and violent ideologies in the area," the British Defence Secretary the minister said.
RAF aircraft have carried out overwatch operations over Syrian airspace to "prevent any efforts to regroup" of IS subsequent to its routing at the battle of Baghuz in 2019, the MoD reported.
"I want to thank all the members of British forces involved in this mission for their skill and their courage," the Defence Secretary added. "They were part of a great many British personnel stationed over the festive period. This operation, to take out militants who pose a risk to our way of life, highlights how UK forces are ready to step up, throughout the year, ensuring Britain's security domestically and influential overseas."
In December, the American forces executed what it described as a "major assault" on IS targets in Syria, subsequent to an assault resulted in the deaths of two US servicemembers and a civilian interpreter in Palmyra.
The UN estimates IS still has between 5,000 and 7,000 militants in both countries.
