British Air Force Typhoon jets have conducted a mission with French warplanes in a coordinated attack targeting an underground arms cache in Syrian territory used by the IS group, as stated by the UK Ministry of Defence.
The facility, located using reconnaissance, was assessed as housing weapons and explosive materials, the announcement noted, and was located in hills just above the historic site of Palmyra in Syria's central region.
"Our aircraft employed laser-guided Paveway IV weapons to strike a several access tunnels down to the depot... preliminary assessments are that the strike was effective," the ministry announced.
There was no evidence of any civilian casualties in the operation on Saturday evening and each participating jet made a safe return, the ministry further stated.
The Typhoon fighters were supported by a Voyager refuelling tanker.
Daesh - referred to as Daesh - imposed extremist governance over significant areas in Iraq and Syria before its territorial defeat in 2019.
"This action demonstrates the UK's leading role, and determination to operate in unison with allied nations, to stamp out any revival of the terrorist group and their violent and radical beliefs in the Middle East," the British Defence Secretary the minister stated.
British military aircraft have conducted patrols over Syria to "forestall any attempted resurgence" of IS subsequent to its defeat at the battle of Baghuz in 2019, the authorities noted.
"I must thank all the members of British forces participating in this operation for their skill and their bravery," the Defence Secretary added. "They were part of numerous UK service members on duty over the holidays. This action, to eliminate militants who pose a risk to our way of life, highlights how UK forces are prepared to act, throughout the year, keeping Britain secure domestically and strong abroad."
During December, the US military executed what it termed a "large-scale strike" against Islamic State objectives in Syria, subsequent to an attack resulted in the deaths of two US troops and a civilian interpreter in the Palmyra area.
The United Nations says Islamic State still maintains roughly 5-7 thousand combatants in both countries.
