British Air Force Typhoon FGR4s have joined forces with French warplanes in a joint strike targeting an hidden munitions depot in Syria employed by the Daesh militant organization, as stated by the British defence ministry.
The site, located using reconnaissance, was believed to be housing weapons and explosive materials, the release indicated, and was located in mountainous terrain just to the north of the historic site of Palmyra in the heart of Syria.
"Our aircraft used Paveway IV guided bombs to strike a number of approach shafts leading to the site... early reports suggest the target was engaged successfully," the MoD said.
There was no indication of any civilian casualties in the strike conducted Saturday night and every plane involved returned safely, the MoD added.
The British jets were assisted by a Voyager refuelling tanker.
The Islamic State group - alternatively referred to as ISIS - imposed jihadist rule over significant areas in Iraq and Syria prior to its 2019 collapse.
"This operation demonstrates the UK's leading role, and commitment to stand shoulder to shoulder with our allies, to eliminate any re-emergence of IS and their violent and radical beliefs in the Middle East," Britain's Defence Chief the Defence Secretary stated.
UK warplanes have conducted patrols over Syrian airspace to "deter any attempted comeback" of Islamic State following its routing at the battle of Baghuz in 2019, the authorities noted.
"I extend gratitude to all the members of British forces who took part in this strike for their expertise and their courage," Healey said. "Including them were a great many British troops on duty over Christmas and New Year. This mission, to eliminate terrorist threats who pose a risk to our safety, demonstrates how British military are prepared to act, throughout the year, ensuring Britain's security at home and powerful internationally."
Last December, the US military conducted what it described as a "major assault" on IS targets in Syria, after an ambush killed two American soldiers and a civilian linguist in the Palmyra area.
The United Nations says IS still boasts an estimated 5,000 to 7,000 combatants in both countries.
