Royal Air Force Typhoon jets have joined forces with French aircraft in a coordinated attack against an hidden munitions depot in Syria employed by the IS group, per a report from the UK Ministry of Defence.
The location, identified by reconnaissance, was assessed as containing munitions and bombs, the statement said, and was situated in hills just north of the ancient city of Palmyra in central Syria.
"The RAF jets utilized Paveway IV guided bombs to target a number of entry passages providing entry to the facility... preliminary assessments indicate the objective was successfully hit," officials stated.
There was no sign of any harm to civilians in the strike late on Saturday and all the aircraft returned to base without incident, the MoD added.
The Typhoon fighters were assisted by a Voyager aerial refuelling aircraft.
IS - also known as Daesh - enforced extremist governance over parts of Iraq and Syria until 2019.
"This operation demonstrates our UK leadership, and determination to stand shoulder to shoulder with our partners, to stamp out any resurgence of the terrorist group and their dangerous and violent ideologies in the region," UK Defence Secretary the Defence Secretary remarked.
RAF aircraft have conducted patrols over Syria to "prevent any attempted resurgence" of Islamic State after its routing at the Baghuz confrontation in 2019, the ministry said.
"I want to thank all the members of the UK armed forces involved in this strike for their expertise and their bravery," Healey added. "Including them were a great many British personnel on duty over the holidays. This action, to take out militants who endanger our security, shows how our armed forces are always on standby, continuously, ensuring Britain's security at home and strong abroad."
Last December, the United States armed forces executed what it called a "massive strike" against IS targets in the country, after an attack claimed the lives of two US servicemembers and a local interpreter in Palmyra.
The United Nations says Daesh still maintains an estimated 5,000 to 7,000 militants in Iraq and Syria.
