British Air Force Typhoon fighter aircraft have conducted a mission with French aircraft in a coordinated attack against an hidden munitions depot in Syrian territory used by the IS group, according to the UK Ministry of Defence.
The facility, identified by reconnaissance, was believed to be containing munitions and bombs, the release indicated, and was positioned in hills just above the historic site of Palmyra in central Syria.
"The RAF jets used laser-guided Paveway IV weapons to hit a several entry passages down to the facility... preliminary assessments suggest the strike was effective," the ministry announced.
There was no indication of any civilian casualties in the operation late on Saturday and all the aircraft made a safe return, the ministry further stated.
The British jets were assisted by a Voyager tanker plane.
IS - referred to as ISIS - imposed extremist governance over large swathes of Iraq and Syria until 2019.
"This operation demonstrates British leadership, and commitment to work closely with our partners, to eradicate any revival of IS and their violent and radical beliefs in the region," Britain's Defence Chief the Defence Secretary remarked.
British military aircraft have performed overwatch operations over Syrian airspace to "deter any efforts to regroup" of IS following its military defeat at the Baghuz confrontation in the year 2019, the authorities noted.
"I extend gratitude to the personnel of the UK armed forces involved in this operation for their expertise and their valour," Healey added. "Including them were a great many British troops deployed over the holidays. This operation, to take out dangerous terrorists who threaten our safety, demonstrates how British military are always on standby, throughout the year, keeping Britain secure within its borders and influential overseas."
In December, the United States armed forces carried out what it called a "massive strike" on Islamic State objectives in the country, subsequent to an ambush resulted in the deaths of two US troops and a local interpreter in Palmyra.
The UN estimates Islamic State still maintains roughly 5-7 thousand fighters in Syria and Iraq.
