British Air Force Typhoon FGR4s have conducted a mission with French warplanes in a joint strike targeting an underground arms cache in Syria employed by the Daesh militant organization, according to the UK's MoD.
The location, identified by reconnaissance, was thought to be housing weapons and explosive materials, the announcement noted, and was situated in hills just to the north of the ancient city of Palmyra in central Syria.
"Our fighter planes employed Paveway IV guided bombs to hit a number of approach shafts leading to the site... preliminary assessments indicate the strike was effective," officials stated.
There was no indication of any civilian casualties in the strike on Saturday evening and all the aircraft returned safely, the defence officials confirmed.
The British jets were supported by a Voyager tanker plane.
Daesh - also known as Daesh - enforced extremist governance over large swathes of Syria and Iraq before its territorial defeat in 2019.
"This operation demonstrates British leadership, and resolve to stand shoulder to shoulder with our partners, to eliminate any resurgence of IS and their harmful and extremist ideologies in the area," Britain's Defence Chief the Defence Secretary remarked.
UK warplanes have carried out patrols over Syria to "prevent any efforts to regroup" of IS following its military defeat at the Baghuz confrontation in 2019, the authorities noted.
"I extend gratitude to all the members of British forces involved in this mission for their skill and their valour," the Defence Secretary said. "They were among numerous UK service members deployed over the festive period. This operation, to eliminate terrorist threats who threaten our way of life, shows how UK forces are always on standby, throughout the year, protecting the UK domestically and powerful internationally."
In December, the United States armed forces conducted what it termed a "major assault" on Daesh sites in the country, subsequent to an attack claimed the lives of two US troops and a civilian interpreter in the Palmyra area.
The United Nations estimates IS still has roughly 5-7 thousand combatants in both countries.
