British Air Force Typhoon fighter aircraft have joined forces with French warplanes in a combined operation against an underground arms cache in Syria operated by the Daesh militant organization, per a report from the UK Ministry of Defence.
The facility, identified by surveillance, was assessed as storing arms and explosives, the statement said, and was positioned in mountains just north of Palmyra in the heart of Syria.
"Our aircraft employed laser-guided Paveway IV weapons to hit a series of approach shafts providing entry to the site... initial indications are that the objective was successfully hit," the ministry announced.
There was no indication of any civilian casualties in the attack conducted Saturday night and all the aircraft returned to base without incident, the ministry further stated.
The British jets were supported by a Voyager tanker plane.
IS - alternatively referred to as ISIS - established jihadist rule over large swathes of Iraq and Syria before its territorial defeat in 2019.
"This action shows the UK's leading role, and determination to operate in unison with allied nations, to eliminate any re-emergence of IS and their dangerous and violent ideologies in the region," the British Defence Secretary the minister said.
RAF aircraft have conducted overwatch operations over Syria to "deter any attempted resurgence" of IS following its defeat at the battle of Baghuz in 2019, the MoD reported.
"I must thank every member of British forces who took part in this operation for their expertise and their courage," he commented. "They were part of numerous British troops deployed over the holidays. This operation, to take out terrorist threats who endanger our security, highlights how our armed forces are ready to step up, all year round, protecting the UK domestically and strong abroad."
During December, the United States armed forces carried out what it described as a "massive strike" on Daesh sites in Syria, subsequent to an assault resulted in the deaths of two US servicemembers and a local interpreter in the Palmyra area.
The United Nations says Islamic State still maintains roughly 5-7 thousand fighters in both countries.
