British Air Force Typhoon FGR4s have joined forces with French warplanes in a combined operation targeting an hidden munitions depot in Syrian territory employed by the IS group, as stated by the UK Ministry of Defence.
The facility, identified by reconnaissance, was assessed as storing arms and explosives, the release indicated, and was positioned in mountains just north of the ancient city of Palmyra in Syria's central region.
"Our aircraft employed Paveway IV guided bombs to strike a several entry passages leading to the facility... preliminary assessments are that the strike was effective," the MoD said.
There was no indication of any civilian impact in the strike late on Saturday and every plane involved returned to base without incident, the ministry further stated.
The British jets were supported by a Voyager aerial refuelling aircraft.
IS - referred to as the so-called Islamic State - established militant control over parts of both Syria and Iraq before its territorial defeat in 2019.
"This action underscores the UK's leading role, and determination to operate in unison with our allies, to stamp out any resurgence of the terrorist group and their violent and radical beliefs in the area," Britain's Defence Chief the minister said.
UK warplanes have carried out overwatch operations over Syria to "prevent any attempted comeback" of IS following its routing at the Baghuz confrontation in the year 2019, the authorities noted.
"I extend gratitude to all the members of British forces who took part in this operation for their professionalism and their courage," he commented. "Including them were thousands of British troops deployed over the holidays. This mission, to take out terrorist threats who pose a risk to our way of life, demonstrates how UK forces are ready to step up, continuously, ensuring Britain's security domestically and strong abroad."
Last December, the American forces carried out what it described as a "large-scale strike" on Islamic State objectives in the country, following an ambush claimed the lives of two US troops and a civilian interpreter in the Palmyra area.
The UN says Daesh still boasts between 5,000 and 7,000 fighters in both countries.
