British Air Force Typhoon FGR4s have conducted a mission with France's air force in a joint strike targeting an underground arms cache in Syria employed by the IS group, per a report from the British defence ministry.
The facility, pinpointed through intelligence, was thought to be containing munitions and bombs, the statement said, and was situated in mountainous terrain just above the ancient city of Palmyra in central Syria.
"The RAF jets employed precision-guided Paveway IV munitions to hit a series of access tunnels providing entry to the facility... early reports suggest the objective was successfully hit," the MoD said.
There was no evidence of any harm to civilians in the strike on Saturday evening and every plane involved returned to base without incident, the MoD added.
The Typhoon fighters were supported by a Voyager tanker plane.
IS - referred to as ISIS - enforced jihadist rule over large swathes of Iraq and Syria before its territorial defeat in 2019.
"This action demonstrates our UK leadership, and resolve to work closely with allied nations, to stamp out any revival of the terrorist group and their dangerous and violent ideologies in the region," UK Defence Secretary the minister stated.
British military aircraft have carried out patrols over Syrian airspace to "forestall any attempted comeback" of the group subsequent to its defeat at the battle of Baghuz in the year 2019, the ministry said.
"I extend gratitude to the personnel of our armed forces who took part in this strike for their skill and their courage," the Defence Secretary commented. "They were among a great many UK service members on duty over the festive period. This mission, to remove militants who threaten our way of life, demonstrates how our armed forces are prepared to act, continuously, ensuring Britain's security at home and powerful internationally."
Last December, the US military carried out what it termed a "major assault" against Daesh sites in the country, following an ambush resulted in the deaths of two US servicemembers and a civilian interpreter in Palmyra.
The UN reports Islamic State still maintains roughly 5-7 thousand combatants in Iraq and Syria.
