British Air Force Typhoon fighter aircraft have conducted a mission with France's air force in a combined operation against an hidden munitions depot in Syrian territory operated by the Daesh militant organization, according to the UK's MoD.
The facility, located using intelligence, was assessed as storing arms and explosives, the statement said, and was situated in mountainous terrain just to the north of the ancient city of Palmyra in Syria's central region.
"Our aircraft utilized laser-guided Paveway IV weapons to target a series of entry passages leading to the facility... early reports are that the objective was successfully hit," the ministry announced.
There was no sign of any civilian impact in the operation on Saturday evening and every plane involved made a safe return, the defence officials confirmed.
The Typhoon FGR4s were assisted by a Voyager tanker plane.
The Islamic State group - referred to as ISIS - imposed extremist governance over parts of Iraq and Syria before its territorial defeat in 2019.
"This strike demonstrates our UK leadership, and commitment to operate in unison with our partners, to eradicate any resurgence of Daesh and their harmful and extremist ideologies in the region," UK Defence Secretary the minister said.
UK warplanes have conducted patrols over Syria to "deter any efforts to regroup" of IS subsequent to its defeat at the Baghuz confrontation in 2019, the ministry said.
"I extend gratitude to the personnel of British forces participating in this operation for their professionalism and their courage," the Defence Secretary said. "Including them were thousands of British troops stationed over the festive period. This operation, to take out dangerous terrorists who threaten our safety, demonstrates how UK forces are prepared to act, continuously, keeping Britain secure domestically and powerful internationally."
Last December, the US military carried out what it described as a "major assault" against Islamic State objectives in Syria, following an attack claimed the lives of two US servicemembers and a civilian interpreter in the Palmyra area.
The United Nations reports Islamic State still has between 5,000 and 7,000 combatants in Syria and Iraq.
