British Air Force Typhoon FGR4s have operated alongside French warplanes in a combined operation targeting an hidden munitions depot in Syrian territory operated by the IS group, as stated by the UK's MoD.
The site, located using intelligence, was believed to be containing munitions and bombs, the release indicated, and was located in mountains just to the north of the historic site of Palmyra in central Syria.
"The RAF jets employed precision-guided Paveway IV munitions to target a number of access tunnels providing entry to the site... initial indications are that the objective was successfully hit," the MoD said.
There was no sign of any civilian casualties in the operation conducted Saturday night and all the aircraft returned safely, the defence officials confirmed.
The Typhoon FGR4s were supported by a Voyager refuelling tanker.
IS - also known as the so-called Islamic State - enforced militant control over significant areas in Syria and Iraq before its territorial defeat in 2019.
"This strike underscores British leadership, and resolve to stand shoulder to shoulder with our allies, to stamp out any revival of Daesh and their violent and radical beliefs in the area," Britain's Defence Chief John Healey said.
RAF aircraft have performed overwatch operations over Syrian airspace to "deter any attempted comeback" of IS subsequent to its routing at the climactic battle in Baghuz in 2019, the authorities noted.
"I must thank all the members of our armed forces who took part in this mission for their skill and their bravery," Healey added. "They were among thousands of British personnel deployed over Christmas and New Year. This action, to take out dangerous terrorists who threaten our way of life, demonstrates how UK forces are prepared to act, continuously, protecting the UK at home and powerful internationally."
During December, the US military executed what it described as a "major assault" on IS targets in Syria, subsequent to an ambush killed two US troops and a civilian linguist in the Palmyra area.
The UN estimates Daesh still boasts roughly 5-7 thousand fighters in both countries.
