British Air Force Typhoon FGR4s have joined forces with France's air force in a coordinated attack against an subterranean weapons facility in Syrian territory operated by the Islamic State group (IS), according to the British defence ministry.
The location, located using reconnaissance, was believed to be housing weapons and explosive materials, the statement said, and was positioned in mountainous terrain just north of Palmyra in the heart of Syria.
"The RAF jets employed Paveway IV guided bombs to hit a several access tunnels down to the facility... initial indications indicate the strike was effective," the ministry announced.
There was no sign of any civilian casualties in the attack conducted Saturday night and each participating jet made a safe return, the MoD added.
The Typhoon fighters were assisted by a Voyager tanker plane.
Daesh - alternatively referred to as Daesh - enforced jihadist rule over significant areas in Iraq and Syria until 2019.
"This strike underscores our UK leadership, and resolve to work closely with allied nations, to stamp out any re-emergence of the terrorist group and their harmful and extremist ideologies in the area," UK Defence Secretary the minister stated.
British military aircraft have conducted overwatch operations over Syria to "deter any efforts to regroup" of IS following its defeat at the battle of Baghuz in 2019, the MoD reported.
"I must thank the personnel of our armed forces who took part in this mission for their expertise and their bravery," the Defence Secretary added. "They were part of a great many British personnel on duty over the holidays. This mission, to remove militants who threaten our way of life, demonstrates how our armed forces are always on standby, throughout the year, ensuring Britain's security within its borders and influential overseas."
Last December, the United States armed forces conducted what it termed a "massive strike" against Islamic State objectives in the country, subsequent to an attack resulted in the deaths of two US troops and a local interpreter in the Palmyra area.
The United Nations says Islamic State still maintains between 5,000 and 7,000 militants in both countries.
