RAF Typhoon fighter aircraft have operated alongside French warplanes in a coordinated attack against an subterranean weapons facility in Syrian territory used by the IS group, as stated by the UK Ministry of Defence.
The facility, located using surveillance, was assessed as containing munitions and bombs, the announcement noted, and was located in hills just above the historic site of Palmyra in central Syria.
"Our aircraft employed Paveway IV guided bombs to target a series of access tunnels leading to the depot... early reports indicate the objective was successfully hit," officials stated.
There was no sign of any civilian casualties in the operation conducted Saturday night and each participating jet returned to base without incident, the defence officials confirmed.
The Typhoon fighters were supported by a Voyager tanker plane.
IS - also known as ISIS - enforced jihadist rule over parts of both Syria and Iraq before its territorial defeat in 2019.
"This strike shows our UK leadership, and resolve to operate in unison with allied nations, to eradicate any revival of Daesh and their violent and radical beliefs in the area," UK Defence Secretary the minister said.
RAF aircraft have performed patrols over Syrian airspace to "forestall any efforts to regroup" of the group following its routing at the climactic battle in Baghuz in 2019, the MoD reported.
"I must thank all the members of our armed forces involved in this mission for their expertise and their bravery," he added. "They were part of numerous British troops deployed over the holidays. This operation, to eliminate militants who endanger our security, shows how British military are always on standby, all year round, keeping Britain secure domestically and powerful internationally."
Last December, the American forces conducted what it called a "large-scale strike" targeting IS targets in Syria, after an attack claimed the lives of two American soldiers and a civilian linguist in Palmyra.
The U.N. says Daesh still has between 5,000 and 7,000 combatants in Iraq and Syria.
