British Air Force Typhoon fighter aircraft have conducted a mission with French warplanes in a coordinated attack targeting an hidden munitions depot in Syrian territory operated by the IS group, as stated by the British defence ministry.
The location, located using reconnaissance, was believed to be storing arms and explosives, the statement said, and was positioned in mountains just above Palmyra in the heart of Syria.
"The RAF jets used precision-guided Paveway IV munitions to strike a number of entry passages leading to the site... initial indications indicate the strike was effective," officials stated.
There was no sign of any harm to civilians in the strike on Saturday evening and each participating jet made a safe return, the defence officials confirmed.
The Typhoon FGR4s were backed up by a Voyager aerial refuelling aircraft.
IS - alternatively referred to as ISIS - enforced militant control over parts of both Syria and Iraq prior to its 2019 collapse.
"This strike underscores British leadership, and commitment to operate in unison with allied nations, to eliminate any resurgence of the terrorist group and their violent and radical beliefs in the region," the British Defence Secretary the Defence Secretary remarked.
British military aircraft have conducted patrols over Syrian airspace to "forestall any efforts to regroup" of IS following its routing at the battle of Baghuz in 2019, the MoD reported.
"I want to thank the personnel of the UK armed forces involved in this mission for their professionalism and their courage," he said. "They were part of a great many UK service members stationed over the festive period. This mission, to take out dangerous terrorists who pose a risk to our way of life, highlights how British military are prepared to act, all year round, ensuring Britain's security within its borders and powerful internationally."
During December, the United States armed forces carried out what it termed a "massive strike" against Daesh sites in Syria, subsequent to an assault killed two US servicemembers and a civilian interpreter in the Palmyra area.
The UN estimates IS still boasts between 5,000 and 7,000 militants in Iraq and Syria.
