RAF Typhoon fighter aircraft have joined forces with France's air force in a joint strike targeting an hidden munitions depot in Syria used by the IS group, per a report from the British defence ministry.
The facility, located using intelligence, was thought to be housing weapons and explosive materials, the release indicated, and was positioned in mountains just to the north of the ancient city of Palmyra in central Syria.
"Our fighter planes employed laser-guided Paveway IV weapons to hit a number of access tunnels down to the site... preliminary assessments are that the strike was effective," the ministry announced.
There was no sign of any harm to civilians in the operation conducted Saturday night and every plane involved made a safe return, the MoD added.
The Typhoon fighters were supported by a Voyager aerial refuelling aircraft.
Daesh - referred to as Daesh - established jihadist rule over large swathes of Iraq and Syria until 2019.
"This action underscores the UK's leading role, and commitment to operate in unison with our partners, to eliminate any re-emergence of IS and their harmful and extremist ideologies in the Middle East," the British Defence Secretary the minister said.
British military aircraft have carried out overwatch operations over Syrian airspace to "prevent any attempted comeback" of Islamic State after its routing at the climactic battle in Baghuz in 2019, the ministry said.
"I want to thank all the members of British forces involved in this mission for their expertise and their valour," the Defence Secretary added. "They were part of a great many UK service members on duty over the holidays. This mission, to remove militants who pose a risk to our way of life, shows how our armed forces are ready to step up, all year round, protecting the UK within its borders and powerful internationally."
During December, the United States armed forces executed what it termed a "large-scale strike" against Islamic State objectives in Syria, following an attack resulted in the deaths of two American soldiers and a civilian linguist in Palmyra.
The UN says Daesh still maintains between 5,000 and 7,000 fighters in Iraq and Syria.
