British Air Force Typhoon fighter aircraft have operated alongside French aircraft in a coordinated attack against an subterranean weapons facility in Syria used by the Daesh militant organization, per a report from the UK's MoD.
The location, pinpointed through reconnaissance, was thought to be storing arms and explosives, the announcement noted, and was positioned in mountainous terrain just above Palmyra in Syria's central region.
"The RAF jets employed Paveway IV guided bombs to hit a number of approach shafts providing entry to the facility... early reports indicate the target was engaged successfully," officials stated.
There was no sign of any civilian casualties in the operation conducted Saturday night and each participating jet returned safely, the MoD added.
The Typhoon FGR4s were supported by a Voyager tanker plane.
The Islamic State group - alternatively referred to as ISIS - established militant control over large swathes of Syria and Iraq before its territorial defeat in 2019.
"This operation underscores our UK leadership, and commitment to stand shoulder to shoulder with our allies, to eliminate any revival of IS and their dangerous and violent ideologies in the area," UK Defence Secretary the Defence Secretary remarked.
UK warplanes have carried out overwatch operations over Syria to "forestall any efforts to regroup" of the group following its military defeat at the Baghuz confrontation in 2019, the MoD reported.
"I want to thank the personnel of the UK armed forces participating in this strike for their professionalism and their valour," he said. "They were part of a great many UK service members on duty over the festive period. This action, to take out terrorist threats who pose a risk to our security, highlights how UK forces are ready to step up, continuously, ensuring Britain's security domestically and strong abroad."
In December, the US military conducted what it described as a "massive strike" against IS targets in Syria, following an assault resulted in the deaths of two US servicemembers and a local interpreter in Palmyra.
The United Nations estimates Daesh still has an estimated 5,000 to 7,000 combatants in Syria and Iraq.
