Royal Air Force Typhoon FGR4s have conducted a mission with French warplanes in a combined operation against an hidden munitions depot in Syrian territory employed by the IS group, per a report from the UK Ministry of Defence.
The facility, identified by surveillance, was assessed as containing munitions and bombs, the announcement noted, and was situated in mountainous terrain just north of the historic site of Palmyra in Syria's central region.
"Our aircraft employed precision-guided Paveway IV munitions to hit a several access tunnels providing entry to the depot... preliminary assessments suggest the target was engaged successfully," the MoD said.
There was no indication of any civilian impact in the attack conducted Saturday night and each participating jet made a safe return, the ministry further stated.
The British jets were supported by a Voyager refuelling tanker.
Daesh - also known as Daesh - imposed jihadist rule over parts of Syria and Iraq before its territorial defeat in 2019.
"This operation shows the UK's leading role, and resolve to operate in unison with our allies, to stamp out any re-emergence of IS and their dangerous and violent ideologies in the region," the British Defence Secretary John Healey stated.
RAF aircraft have conducted patrols over Syrian airspace to "prevent any attempted comeback" of the group subsequent to its defeat at the Baghuz confrontation in 2019, the ministry said.
"I want to thank the personnel of our armed forces who took part in this operation for their expertise and their valour," the Defence Secretary said. "Including them were thousands of British personnel stationed over the holidays. This mission, to take out militants who endanger our security, shows how British military are prepared to act, all year round, protecting the UK at home and influential overseas."
Last December, the US military executed what it termed a "large-scale strike" on Islamic State objectives in Syria, following an assault killed two US troops and a civilian linguist in Palmyra.
The UN says Daesh still boasts between 5,000 and 7,000 combatants in Syria and Iraq.
