RAF Typhoon FGR4s have conducted a mission with French aircraft in a joint strike on an underground arms cache in Syrian territory operated by the Daesh militant organization, per a report from the British defence ministry.
The location, pinpointed through reconnaissance, was assessed as containing munitions and bombs, the statement said, and was situated in hills just to the north of the historic site of Palmyra in Syria's central region.
"The RAF jets employed precision-guided Paveway IV munitions to target a several access tunnels leading to the facility... preliminary assessments indicate the strike was effective," the MoD said.
There was no sign of any civilian casualties in the attack late on Saturday and every plane involved made a safe return, the defence officials confirmed.
The Typhoon fighters were assisted by a Voyager refuelling tanker.
IS - alternatively referred to as ISIS - enforced extremist governance over parts of Syria and Iraq until 2019.
"This action demonstrates the UK's leading role, and commitment to operate in unison with our allies, to eliminate any resurgence of the terrorist group and their violent and radical beliefs in the region," UK Defence Secretary the Defence Secretary remarked.
UK warplanes have performed patrols over Syrian airspace to "forestall any attempted comeback" of IS after its routing at the battle of Baghuz in 2019, the MoD reported.
"I extend gratitude to every member of British forces involved in this mission for their expertise and their valour," Healey added. "They were among a great many British personnel deployed over the holidays. This action, to remove terrorist threats who threaten our way of life, shows how UK forces are always on standby, continuously, keeping Britain secure domestically and strong abroad."
In December, the United States armed forces conducted what it described as a "massive strike" against Daesh sites in the country, following an ambush resulted in the deaths of two US servicemembers and a civilian linguist in Palmyra.
The UN says Daesh still boasts roughly 5-7 thousand combatants in Syria and Iraq.
