British Air Force Typhoon jets have joined forces with France's air force in a coordinated attack on an subterranean weapons facility in Syrian territory operated by the IS group, per a report from the UK's MoD.
The site, pinpointed through intelligence, was assessed as storing arms and explosives, the announcement noted, and was located in hills just to the north of the historic site of Palmyra in Syria's central region.
"Our aircraft utilized precision-guided Paveway IV munitions to target a several approach shafts down to the site... initial indications indicate the target was engaged successfully," officials stated.
There was no indication of any civilian impact in the strike late on Saturday and all the aircraft returned to base without incident, the MoD added.
The Typhoon fighters were backed up by a Voyager refuelling tanker.
Daesh - referred to as ISIS - enforced jihadist rule over large swathes of Iraq and Syria until 2019.
"This operation shows our UK leadership, and determination to stand shoulder to shoulder with our allies, to eliminate any re-emergence of the terrorist group and their dangerous and violent ideologies in the region," the British Defence Secretary John Healey remarked.
British military aircraft have conducted patrols over Syrian airspace to "forestall any attempted comeback" of the group subsequent to its routing at the climactic battle in Baghuz in 2019, the MoD reported.
"I extend gratitude to the personnel of British forces who took part in this strike for their skill and their courage," Healey added. "They were part of a great many UK service members deployed over the festive period. This operation, to take out terrorist threats who pose a risk to our safety, shows how British military are always on standby, all year round, keeping Britain secure at home and powerful internationally."
During December, the American forces carried out what it described as a "large-scale strike" targeting Daesh sites in the country, after an attack claimed the lives of two US servicemembers and a local interpreter in Palmyra.
The UN reports IS still boasts between 5,000 and 7,000 fighters in Syria and Iraq.
