British Air Force Typhoon fighter aircraft have conducted a mission with France's air force in a joint strike on an hidden munitions depot in Syria used by the IS group, per a report from the British defence ministry.
The facility, located using surveillance, was believed to be housing weapons and explosive materials, the statement said, and was positioned in mountainous terrain just north of the ancient city of Palmyra in Syria's central region.
"Our aircraft used Paveway IV guided bombs to strike a several entry passages leading to the facility... initial indications are that the objective was successfully hit," the ministry announced.
There was no indication of any harm to civilians in the strike late on Saturday and all the aircraft returned to base without incident, the defence officials confirmed.
The Typhoon FGR4s were supported by a Voyager refuelling tanker.
Daesh - referred to as Daesh - established militant control over large swathes of Iraq and Syria prior to its 2019 collapse.
"This operation shows the UK's leading role, and resolve to operate in unison with our allies, to eradicate any revival of the terrorist group and their violent and radical beliefs in the area," Britain's Defence Chief John Healey remarked.
RAF aircraft have performed overwatch operations over Syria to "deter any attempted comeback" of Islamic State following its defeat at the Baghuz confrontation in the year 2019, the MoD reported.
"I must thank all the members of the UK armed forces involved in this mission for their professionalism and their valour," he added. "Including them were numerous UK service members deployed over the holidays. This mission, to take out militants who endanger our security, shows how British military are always on standby, throughout the year, protecting the UK within its borders and strong abroad."
In December, the US military executed what it described as a "major assault" on Daesh sites in Syria, after an attack killed two US troops and a civilian linguist in Palmyra.
The United Nations estimates IS still has roughly 5-7 thousand fighters in Iraq and Syria.
