Royal Air Force Typhoon jets have joined forces with France's air force in a joint strike targeting an hidden munitions depot in Syria used by the IS group, per a report from the British defence ministry.
The site, pinpointed through surveillance, was assessed as storing arms and explosives, the statement said, and was situated in hills just north of the ancient city of Palmyra in Syria's central region.
"Our aircraft used Paveway IV guided bombs to target a several approach shafts leading to the depot... early reports indicate the objective was successfully hit," the MoD said.
There was no indication of any civilian casualties in the attack conducted Saturday night and every plane involved returned safely, the MoD added.
The Typhoon fighters were supported by a Voyager tanker plane.
IS - alternatively referred to as Daesh - established extremist governance over parts of Iraq and Syria prior to its 2019 collapse.
"This action underscores the UK's leading role, and determination to stand shoulder to shoulder with our partners, to eradicate any resurgence of IS and their harmful and extremist ideologies in the Middle East," UK Defence Secretary the Defence Secretary stated.
British military aircraft have conducted patrols over Syria to "deter any efforts to regroup" of IS following its defeat at the Baghuz confrontation in 2019, the authorities noted.
"I want to thank all the members of British forces who took part in this strike for their expertise and their bravery," the Defence Secretary added. "Including them were thousands of UK service members stationed over the holidays. This action, to remove dangerous terrorists who threaten our way of life, shows how our armed forces are always on standby, all year round, ensuring Britain's security domestically and strong abroad."
During December, the American forces conducted what it described as a "large-scale strike" on Islamic State objectives in the country, after an ambush resulted in the deaths of two American soldiers and a local interpreter in the Palmyra area.
The United Nations estimates Islamic State still has roughly 5-7 thousand militants in both countries.
