Royal Air Force Typhoon fighter aircraft have joined forces with French warplanes in a joint strike against an hidden munitions depot in Syria employed by the IS group, as stated by the UK's MoD.
The facility, pinpointed through surveillance, was thought to be containing munitions and bombs, the announcement noted, and was positioned in mountainous terrain just to the north of the ancient city of Palmyra in the heart of Syria.
"Our fighter planes employed precision-guided Paveway IV munitions to hit a series of approach shafts leading to the facility... preliminary assessments indicate the strike was effective," the MoD said.
There was no sign of any civilian casualties in the attack conducted Saturday night and all the aircraft returned to base without incident, the MoD added.
The Typhoon FGR4s were supported by a Voyager aerial refuelling aircraft.
Daesh - referred to as the so-called Islamic State - enforced militant control over large swathes of Syria and Iraq until 2019.
"This strike underscores British leadership, and determination to stand shoulder to shoulder with our partners, to eliminate any resurgence of IS and their violent and radical beliefs in the Middle East," the British Defence Secretary the Defence Secretary stated.
RAF aircraft have conducted patrols over Syria to "deter any attempted resurgence" of IS after its military defeat at the Baghuz confrontation in 2019, the authorities noted.
"I extend gratitude to every member of the UK armed forces who took part in this strike for their skill and their courage," the Defence Secretary commented. "They were part of thousands of British troops deployed over Christmas and New Year. This action, to take out terrorist threats who endanger our safety, demonstrates how British military are prepared to act, all year round, keeping Britain secure within its borders and powerful internationally."
In December, the US military executed what it termed a "massive strike" targeting Daesh sites in Syria, following an ambush killed two US troops and a civilian linguist in the Palmyra area.
The UN reports IS still maintains between 5,000 and 7,000 militants in Iraq and Syria.
