Royal Air Force Typhoon FGR4s have conducted a mission with France's air force in a coordinated attack against an underground arms cache in Syria operated by the Islamic State group (IS), per a report from the UK's MoD.
The location, located using surveillance, was assessed as storing arms and explosives, the statement said, and was situated in mountainous terrain just to the north of the historic site of Palmyra in central Syria.
"Our aircraft used precision-guided Paveway IV munitions to target a number of entry passages leading to the site... preliminary assessments indicate the target was engaged successfully," officials stated.
There was no indication of any civilian casualties in the strike late on Saturday and every plane involved made a safe return, the defence officials confirmed.
The Typhoon fighters were supported by a Voyager aerial refuelling aircraft.
IS - alternatively referred to as ISIS - imposed extremist governance over significant areas in Syria and Iraq prior to its 2019 collapse.
"This operation demonstrates our UK leadership, and commitment to stand shoulder to shoulder with our allies, to eradicate any resurgence of IS and their harmful and extremist ideologies in the area," the British Defence Secretary the minister said.
UK warplanes have performed surveillance missions over Syrian airspace to "forestall any attempted resurgence" of the group following its military defeat at the battle of Baghuz in 2019, the authorities noted.
"I want to thank all the members of our armed forces who took part in this strike for their expertise and their valour," the Defence Secretary added. "They were part of numerous British personnel on duty over the festive period. This operation, to take out militants who endanger our way of life, demonstrates how UK forces are prepared to act, throughout the year, protecting the UK domestically and influential overseas."
During December, the US military executed what it termed a "major assault" targeting IS targets in the country, subsequent to an ambush resulted in the deaths of two American soldiers and a local interpreter in the Palmyra area.
The UN estimates Islamic State still has an estimated 5,000 to 7,000 fighters in both countries.
