Royal Air Force Typhoon jets have conducted a mission with France's air force in a coordinated attack targeting an subterranean weapons facility in Syria used by the Daesh militant organization, as stated by the British defence ministry.
The site, located using reconnaissance, was thought to be housing weapons and explosive materials, the release indicated, and was situated in hills just north of the historic site of Palmyra in the heart of Syria.
"The RAF jets used Paveway IV guided bombs to hit a several access tunnels leading to the site... early reports indicate the target was engaged successfully," the MoD said.
There was no indication of any civilian casualties in the strike conducted Saturday night and every plane involved returned to base without incident, the MoD added.
The Typhoon FGR4s were supported by a Voyager tanker plane.
The Islamic State group - referred to as ISIS - established jihadist rule over parts of both Syria and Iraq before its territorial defeat in 2019.
"This operation shows British leadership, and determination to operate in unison with allied nations, to eliminate any re-emergence of the terrorist group and their violent and radical beliefs in the region," UK Defence Secretary the minister stated.
UK warplanes have performed patrols over Syria to "prevent any attempted resurgence" of IS after its military defeat at the climactic battle in Baghuz in the year 2019, the MoD reported.
"I want to thank all the members of our armed forces participating in this mission for their expertise and their courage," the Defence Secretary said. "Including them were thousands of British troops stationed over the holidays. This action, to eliminate terrorist threats who pose a risk to our way of life, shows how UK forces are always on standby, all year round, protecting the UK at home and strong abroad."
Last December, the United States armed forces executed what it called a "large-scale strike" against Islamic State objectives in Syria, following an ambush resulted in the deaths of two US servicemembers and a local interpreter in the Palmyra area.
The United Nations says Daesh still boasts roughly 5-7 thousand fighters in both countries.
