RAF Typhoon jets have conducted a mission with France's air force in a coordinated attack against an hidden munitions depot in Syria employed by the IS group, per a report from the UK's MoD.
The facility, located using intelligence, was thought to be housing weapons and explosive materials, the release indicated, and was situated in hills just to the north of the historic site of Palmyra in central Syria.
"Our aircraft used Paveway IV guided bombs to target a series of access tunnels leading to the site... initial indications suggest the target was engaged successfully," the MoD said.
There was no sign of any civilian impact in the attack late on Saturday and all the aircraft returned safely, the MoD added.
The Typhoon fighters were supported by a Voyager refuelling tanker.
The Islamic State group - alternatively referred to as ISIS - imposed jihadist rule over large swathes of Iraq and Syria until 2019.
"This operation underscores our UK leadership, and determination to operate in unison with our partners, to eradicate any revival of Daesh and their dangerous and violent ideologies in the area," the British Defence Secretary the minister said.
UK warplanes have conducted overwatch operations over Syria to "forestall any efforts to regroup" of the group after its routing at the battle of Baghuz in the year 2019, the ministry said.
"I want to thank all the members of British forces involved in this operation for their expertise and their bravery," he said. "They were among numerous British personnel deployed over Christmas and New Year. This mission, to take out terrorist threats who threaten our security, highlights how UK forces are always on standby, throughout the year, ensuring Britain's security domestically and influential overseas."
During December, the US military carried out what it described as a "major assault" against Daesh sites in the country, subsequent to an ambush resulted in the deaths of two US servicemembers and a civilian interpreter in Palmyra.
The UN says IS still has an estimated 5,000 to 7,000 militants in Syria and Iraq.
