British Air Force Typhoon jets have joined forces with French aircraft in a joint strike against an hidden munitions depot in Syria used by the IS group, as stated by the UK's MoD.
The facility, pinpointed through reconnaissance, was assessed as containing munitions and bombs, the statement said, and was located in hills just north of the ancient city of Palmyra in Syria's central region.
"The RAF jets employed precision-guided Paveway IV munitions to hit a series of entry passages leading to the facility... initial indications suggest the objective was successfully hit," the ministry announced.
There was no sign of any civilian impact in the attack conducted Saturday night and every plane involved returned to base without incident, the ministry further stated.
The British jets were supported by a Voyager aerial refuelling aircraft.
The Islamic State group - alternatively referred to as the so-called Islamic State - established extremist governance over significant areas in Syria and Iraq before its territorial defeat in 2019.
"This strike underscores the UK's leading role, and commitment to operate in unison with our partners, to eliminate any resurgence of Daesh and their dangerous and violent ideologies in the area," Britain's Defence Chief the Defence Secretary said.
RAF aircraft have carried out overwatch operations over Syria to "deter any efforts to regroup" of Islamic State after its defeat at the Baghuz confrontation in the year 2019, the ministry said.
"I want to thank the personnel of our armed forces involved in this operation for their expertise and their courage," Healey added. "Including them were numerous UK service members deployed over the holidays. This operation, to take out militants who threaten our safety, shows how UK forces are prepared to act, continuously, protecting the UK domestically and powerful internationally."
During December, the United States armed forces conducted what it described as a "massive strike" on IS targets in the country, after an assault killed two US servicemembers and a local interpreter in the Palmyra area.
The UN says IS still has between 5,000 and 7,000 fighters in Syria and Iraq.
