British Air Force Typhoon jets have operated alongside France's air force in a joint strike against an subterranean weapons facility in Syrian territory employed by the Daesh militant organization, per a report from the UK's MoD.
The site, pinpointed through surveillance, was thought to be housing weapons and explosive materials, the release indicated, and was located in mountainous terrain just north of Palmyra in Syria's central region.
"The RAF jets employed precision-guided Paveway IV munitions to strike a series of approach shafts providing entry to the facility... preliminary assessments are that the strike was effective," the MoD said.
There was no sign of any civilian casualties in the strike conducted Saturday night and all the aircraft made a safe return, the ministry further stated.
The Typhoon fighters were assisted by a Voyager aerial refuelling aircraft.
Daesh - also known as ISIS - established jihadist rule over large swathes of Syria and Iraq until 2019.
"This operation underscores our UK leadership, and resolve to work closely with our partners, to stamp out any revival of the terrorist group and their harmful and extremist ideologies in the region," Britain's Defence Chief the minister stated.
British military aircraft have performed surveillance missions over Syria to "forestall any attempted resurgence" of the group subsequent to its routing at the Baghuz confrontation in 2019, the MoD reported.
"I want to thank all the members of British forces participating in this mission for their expertise and their bravery," the Defence Secretary commented. "They were part of numerous British personnel stationed over Christmas and New Year. This mission, to eliminate terrorist threats who threaten our safety, demonstrates how our armed forces are always on standby, continuously, ensuring Britain's security within its borders and powerful internationally."
Last December, the American forces executed what it called a "large-scale strike" targeting Daesh sites in the country, following an assault resulted in the deaths of two US servicemembers and a civilian interpreter in Palmyra.
The UN estimates Islamic State still has roughly 5-7 thousand combatants in Iraq and Syria.
