Royal Air Force Typhoon FGR4s have operated alongside French warplanes in a combined operation against an underground arms cache in Syria used by the Islamic State group (IS), as stated by the British defence ministry.
The location, pinpointed through intelligence, was assessed as housing weapons and explosive materials, the release indicated, and was positioned in mountainous terrain just to the north of the historic site of Palmyra in central Syria.
"The RAF jets used precision-guided Paveway IV munitions to strike a several access tunnels leading to the site... early reports suggest the target was engaged successfully," officials stated.
There was no sign of any civilian casualties in the operation late on Saturday and all the aircraft returned to base without incident, the ministry further stated.
The Typhoon fighters were supported by a Voyager tanker plane.
Daesh - also known as ISIS - established militant control over parts of Iraq and Syria before its territorial defeat in 2019.
"This strike shows the UK's leading role, and determination to operate in unison with our partners, to stamp out any revival of the terrorist group and their violent and radical beliefs in the area," the British Defence Secretary the minister remarked.
UK warplanes have performed overwatch operations over Syria to "forestall any efforts to regroup" of Islamic State following its routing at the climactic battle in Baghuz in 2019, the ministry said.
"I want to thank every member of our armed forces involved in this operation for their expertise and their courage," the Defence Secretary said. "They were part of numerous British personnel deployed over the festive period. This action, to eliminate dangerous terrorists who threaten our security, highlights how British military are ready to step up, all year round, ensuring Britain's security within its borders and powerful internationally."
In December, the American forces carried out what it called a "major assault" on IS targets in the country, following an attack resulted in the deaths of two US troops and a civilian interpreter in Palmyra.
The United Nations estimates Daesh still has between 5,000 and 7,000 combatants in Syria and Iraq.
