RAF Typhoon FGR4s have joined forces with French aircraft in a joint strike on an hidden munitions depot in Syria used by the IS group, per a report from the UK's MoD.
The location, identified by intelligence, was assessed as containing munitions and bombs, the release indicated, and was located in hills just to the north of Palmyra in central Syria.
"Our aircraft utilized precision-guided Paveway IV munitions to strike a several entry passages leading to the depot... initial indications indicate the strike was effective," officials stated.
There was no indication of any civilian impact in the strike on Saturday evening and each participating jet returned safely, the defence officials confirmed.
The Typhoon FGR4s were supported by a Voyager aerial refuelling aircraft.
Daesh - referred to as ISIS - imposed extremist governance over large swathes of Iraq and Syria prior to its 2019 collapse.
"This action underscores our UK leadership, and determination to operate in unison with allied nations, to eradicate any revival of IS and their harmful and extremist ideologies in the area," the British Defence Secretary John Healey remarked.
British military aircraft have conducted overwatch operations over Syria to "deter any attempted resurgence" of Islamic State following its routing at the climactic battle in Baghuz in 2019, the authorities noted.
"I want to thank the personnel of British forces who took part in this strike for their skill and their courage," the Defence Secretary added. "They were part of thousands of UK service members on duty over the festive period. This operation, to eliminate terrorist threats who threaten our safety, demonstrates how UK forces are always on standby, all year round, keeping Britain secure at home and influential overseas."
During December, the US military executed what it described as a "large-scale strike" targeting IS targets in the country, subsequent to an assault resulted in the deaths of two American soldiers and a civilian linguist in Palmyra.
The UN reports Daesh still boasts an estimated 5,000 to 7,000 combatants in Iraq and Syria.
