British Air Force Typhoon fighter aircraft have conducted a mission with France's air force in a coordinated attack against an underground arms cache in Syrian territory employed by the IS group, as stated by the British defence ministry.
The site, pinpointed through intelligence, was assessed as housing weapons and explosive materials, the announcement noted, and was located in hills just north of the ancient city of Palmyra in Syria's central region.
"Our fighter planes utilized precision-guided Paveway IV munitions to hit a several entry passages leading to the depot... initial indications indicate the strike was effective," officials stated.
There was no indication of any civilian impact in the operation conducted Saturday night and every plane involved returned to base without incident, the ministry further stated.
The British jets were backed up by a Voyager refuelling tanker.
Daesh - also known as the so-called Islamic State - enforced jihadist rule over large swathes of both Syria and Iraq prior to its 2019 collapse.
"This operation underscores our UK leadership, and resolve to stand shoulder to shoulder with our partners, to eradicate any resurgence of IS and their dangerous and violent ideologies in the region," UK Defence Secretary the Defence Secretary said.
UK warplanes have conducted overwatch operations over Syrian airspace to "deter any attempted resurgence" of Islamic State after its defeat at the climactic battle in Baghuz in the year 2019, the authorities noted.
"I extend gratitude to the personnel of our armed forces involved in this strike for their expertise and their courage," Healey said. "Including them were a great many British personnel stationed over the festive period. This mission, to eliminate terrorist threats who pose a risk to our security, shows how UK forces are ready to step up, throughout the year, keeping Britain secure at home and strong abroad."
In December, the United States armed forces conducted what it called a "massive strike" on IS targets in the country, after an ambush resulted in the deaths of two US troops and a local interpreter in Palmyra.
The United Nations says Daesh still boasts an estimated 5,000 to 7,000 combatants in Syria and Iraq.
