Royal Air Force Typhoon jets have operated alongside France's air force in a combined operation targeting an underground arms cache in Syria operated by the Daesh militant organization, as stated by the British defence ministry.
The site, located using surveillance, was believed to be storing arms and explosives, the announcement noted, and was located in hills just above Palmyra in Syria's central region.
"Our fighter planes used precision-guided Paveway IV munitions to target a number of access tunnels down to the depot... early reports are that the objective was successfully hit," the ministry announced.
There was no indication of any civilian impact in the strike late on Saturday and each participating jet returned to base without incident, the ministry further stated.
The British jets were backed up by a Voyager tanker plane.
Daesh - alternatively referred to as ISIS - enforced extremist governance over large swathes of Syria and Iraq before its territorial defeat in 2019.
"This operation shows the UK's leading role, and determination to operate in unison with our partners, to stamp out any revival of Daesh and their harmful and extremist ideologies in the Middle East," UK Defence Secretary the Defence Secretary said.
British military aircraft have conducted surveillance missions over Syria to "deter any attempted resurgence" of the group following its routing at the battle of Baghuz in 2019, the MoD reported.
"I must thank the personnel of the UK armed forces participating in this strike for their skill and their valour," he added. "They were part of a great many UK service members on duty over the festive period. This mission, to eliminate terrorist threats who endanger our way of life, demonstrates how UK forces are prepared to act, throughout the year, keeping Britain secure at home and strong abroad."
In December, the American forces executed what it called a "major assault" on IS targets in the country, after an ambush killed two US servicemembers and a civilian interpreter in the Palmyra area.
The U.N. reports Islamic State still maintains between 5,000 and 7,000 combatants in Iraq and Syria.
