Royal Air Force Typhoon FGR4s have conducted a mission with France's air force in a joint strike on an subterranean weapons facility in Syria used by the Daesh militant organization, per a report from the UK Ministry of Defence.
The site, pinpointed through reconnaissance, was believed to be housing weapons and explosive materials, the statement said, and was situated in hills just to the north of the ancient city of Palmyra in Syria's central region.
"The RAF jets utilized precision-guided Paveway IV munitions to hit a several approach shafts providing entry to the facility... preliminary assessments suggest the objective was successfully hit," the ministry announced.
There was no indication of any civilian casualties in the attack on Saturday evening and each participating jet returned to base without incident, the defence officials confirmed.
The Typhoon FGR4s were supported by a Voyager aerial refuelling aircraft.
Daesh - also known as the so-called Islamic State - enforced militant control over parts of Iraq and Syria until 2019.
"This strike shows the UK's leading role, and resolve to work closely with allied nations, to eliminate any revival of Daesh and their dangerous and violent ideologies in the Middle East," UK Defence Secretary the Defence Secretary said.
UK warplanes have carried out surveillance missions over Syria to "deter any attempted resurgence" of IS after its military defeat at the climactic battle in Baghuz in 2019, the authorities noted.
"I must thank every member of the UK armed forces participating in this strike for their professionalism and their courage," the Defence Secretary added. "Including them were numerous UK service members stationed over the holidays. This action, to eliminate militants who endanger our safety, demonstrates how British military are prepared to act, continuously, protecting the UK domestically and powerful internationally."
Last December, the American forces executed what it called a "major assault" on Daesh sites in Syria, following an assault resulted in the deaths of two US troops and a civilian interpreter in the Palmyra area.
The United Nations estimates Daesh still has roughly 5-7 thousand militants in Iraq and Syria.
