British Air Force Typhoon fighter aircraft have conducted a mission with French warplanes in a coordinated attack against an hidden munitions depot in Syrian territory operated by the IS group, per a report from the British defence ministry.
The site, pinpointed through surveillance, was thought to be storing arms and explosives, the release indicated, and was situated in mountainous terrain just to the north of Palmyra in central Syria.
"Our aircraft used laser-guided Paveway IV weapons to hit 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 casualties in the operation on Saturday evening and every plane involved returned to base without incident, the MoD added.
The Typhoon fighters were supported by a Voyager refuelling tanker.
The Islamic State group - referred to as ISIS - enforced militant control over significant areas in Iraq and Syria before its territorial defeat in 2019.
"This action underscores our UK leadership, and resolve to operate in unison with allied nations, to eradicate any revival of IS and their harmful and extremist ideologies in the region," UK Defence Secretary the minister remarked.
RAF aircraft have performed surveillance missions over Syria to "forestall any attempted comeback" of IS after its defeat at the Baghuz confrontation in 2019, the MoD reported.
"I extend gratitude to every member of our armed forces participating in this strike for their expertise and their valour," the Defence Secretary added. "They were among a great many British personnel deployed over the holidays. This mission, to remove militants who pose a risk to our security, demonstrates how British military are ready to step up, continuously, keeping Britain secure at home and strong abroad."
During December, the American forces conducted what it termed a "large-scale strike" targeting IS targets in Syria, following an assault resulted in the deaths of two US servicemembers and a civilian linguist in Palmyra.
The U.N. estimates Daesh still boasts between 5,000 and 7,000 fighters in Iraq and Syria.
