Royal Air Force Typhoon jets have conducted a mission with French aircraft in a coordinated attack targeting an underground arms cache in Syria employed by the IS group, as stated by the British defence ministry.
The site, pinpointed through intelligence, was assessed as storing arms and explosives, the announcement noted, and was located in mountains just to the north of the historic site of Palmyra in Syria's central region.
"Our aircraft used laser-guided Paveway IV weapons to strike a series of approach shafts down to the site... preliminary assessments suggest the target was engaged successfully," the ministry announced.
There was no indication of any civilian impact in the strike conducted Saturday night and every plane involved made a safe return, the MoD added.
The British jets were backed up by a Voyager aerial refuelling aircraft.
Daesh - also known as Daesh - established militant control over significant areas in Iraq and Syria until 2019.
"This strike underscores our UK leadership, and determination to operate in unison with our partners, to stamp out any re-emergence of IS and their violent and radical beliefs in the Middle East," UK Defence Secretary the Defence Secretary remarked.
British military aircraft have carried out surveillance missions over Syria to "prevent any attempted resurgence" of IS after its defeat at the Baghuz confrontation in 2019, the MoD reported.
"I want to thank the personnel of our armed forces involved in this mission for their expertise and their bravery," Healey said. "They were part of a great many UK service members deployed over Christmas and New Year. This mission, to eliminate terrorist threats who pose a risk to our way of life, shows how UK forces are prepared to act, continuously, protecting the UK within its borders and strong abroad."
During December, the US military carried out what it described as a "large-scale strike" targeting IS targets in the country, after an attack resulted in the deaths of two US troops and a civilian interpreter in the Palmyra area.
The United Nations says Daesh still has between 5,000 and 7,000 militants in both countries.
