British Air Force Typhoon fighter aircraft have joined forces with French aircraft in a coordinated attack targeting an hidden munitions depot in Syria used by the IS group, per a report from the British defence ministry.
The location, pinpointed through intelligence, was believed to be storing arms and explosives, the statement said, and was situated in hills just to the north of the historic site of Palmyra in central Syria.
"Our aircraft used laser-guided Paveway IV weapons to strike a number of approach shafts providing entry to the facility... early reports indicate the strike was effective," officials stated.
There was no evidence of any harm to civilians in the operation conducted Saturday night and all the aircraft made a safe return, the MoD added.
The British jets were backed up by a Voyager tanker plane.
The Islamic State group - referred to as ISIS - established jihadist rule over parts of Iraq and Syria before its territorial defeat in 2019.
"This action demonstrates the UK's leading role, and commitment to work closely with our partners, to stamp out any re-emergence of Daesh and their harmful and extremist ideologies in the Middle East," UK Defence Secretary the Defence Secretary said.
RAF aircraft have conducted surveillance missions over Syria to "forestall any efforts to regroup" of Islamic State subsequent to its defeat at the Baghuz confrontation in 2019, the MoD reported.
"I extend gratitude to all the members of the UK armed forces participating in this mission for their professionalism and their valour," Healey added. "Including them were thousands of British troops on duty over the festive period. This action, to take out dangerous terrorists who pose a risk to our security, shows how UK forces are always on standby, continuously, protecting the UK domestically and influential overseas."
Last December, the American forces executed what it described as a "massive strike" targeting Islamic State objectives in Syria, subsequent to an assault killed two US servicemembers and a civilian interpreter in Palmyra.
The U.N. says IS still boasts between 5,000 and 7,000 fighters in both countries.
