RAF Typhoon jets have conducted a mission with France's air force in a joint strike targeting an hidden munitions depot in Syrian territory operated by the Daesh militant organization, as stated by the British defence ministry.
The site, located using intelligence, was thought to be storing arms and explosives, the statement said, and was located in hills just above Palmyra in the heart of Syria.
"The RAF jets used precision-guided Paveway IV munitions to strike a series of approach shafts providing entry to the depot... early reports indicate the target was engaged successfully," the MoD said.
There was no sign of any civilian impact in the operation late on Saturday and each participating jet returned to base without incident, the defence officials confirmed.
The British jets were assisted by a Voyager refuelling tanker.
IS - alternatively referred to as ISIS - established jihadist rule over large swathes of both Syria and Iraq prior to its 2019 collapse.
"This strike shows British leadership, and resolve to work closely with our partners, to stamp out any re-emergence of Daesh and their dangerous and violent ideologies in the Middle East," UK Defence Secretary the minister said.
RAF aircraft have performed surveillance missions over Syrian airspace to "forestall any efforts to regroup" of IS following its military defeat at the Baghuz confrontation in the year 2019, the MoD reported.
"I extend gratitude to the personnel of British forces participating in this operation for their expertise and their courage," Healey added. "They were part of thousands of British troops stationed over the festive period. This action, to eliminate terrorist threats who endanger our security, shows how our armed forces are ready to step up, continuously, protecting the UK at home and powerful internationally."
During December, the United States armed forces executed what it called a "massive strike" on Islamic State objectives in Syria, after an ambush claimed the lives of two US troops and a civilian linguist in Palmyra.
The U.N. reports Daesh still has between 5,000 and 7,000 combatants in both countries.
