British Air Force Typhoon FGR4s have joined forces with French aircraft in a coordinated attack on an hidden munitions depot in Syria used by the Daesh militant organization, per a report from the UK Ministry of Defence.
The site, pinpointed through reconnaissance, was believed to be housing weapons and explosive materials, the announcement noted, and was situated in hills just above Palmyra in Syria's central region.
"Our aircraft utilized Paveway IV guided bombs to strike a series of approach shafts providing entry to the facility... initial indications are that the strike was effective," the ministry announced.
There was no evidence of any civilian impact in the attack conducted Saturday night and all the aircraft made a safe return, the MoD added.
The British jets were supported by a Voyager tanker plane.
Daesh - also known as the so-called Islamic State - enforced militant control over parts of Iraq and Syria before its territorial defeat in 2019.
"This strike shows our UK leadership, and determination to work closely with allied nations, to eradicate any re-emergence of the terrorist group and their violent and radical beliefs in the Middle East," the British Defence Secretary the minister said.
UK warplanes have performed surveillance missions over Syrian airspace to "forestall any efforts to regroup" of the group after its defeat at the battle of Baghuz in 2019, the MoD reported.
"I extend gratitude to the personnel of British forces who took part in this operation for their expertise and their bravery," the Defence Secretary added. "They were part of thousands of British troops deployed over the holidays. This mission, to remove dangerous terrorists who pose a risk to our way of life, demonstrates how our armed forces are ready to step up, all year round, keeping Britain secure at home and influential overseas."
Last December, the US military carried out what it called a "large-scale strike" on IS targets in the country, following an attack killed two American soldiers and a local interpreter in the Palmyra area.
The UN reports IS still boasts roughly 5-7 thousand fighters in Iraq and Syria.
