British Air Force Typhoon fighter aircraft have joined forces with France's air force in a joint strike against an hidden munitions depot in Syrian territory used by the IS group, per a report from the UK's MoD.
The site, located using intelligence, was thought to be containing munitions and bombs, the statement said, and was located in hills just above the ancient city of Palmyra in Syria's central region.
"The RAF jets employed laser-guided Paveway IV weapons to target a series of entry passages providing entry to the facility... preliminary assessments suggest the target was engaged successfully," the MoD said.
There was no evidence of any civilian casualties in the operation on Saturday evening and all the aircraft returned to base without incident, the defence officials confirmed.
The British jets were supported by a Voyager tanker plane.
The Islamic State group - also known as Daesh - established extremist governance over large swathes of both Syria and Iraq until 2019.
"This action underscores British leadership, and resolve to work closely with allied nations, to stamp out any resurgence of IS and their harmful and extremist ideologies in the Middle East," Britain's Defence Chief the minister said.
UK warplanes have conducted overwatch operations over Syrian airspace to "prevent any efforts to regroup" of Islamic State subsequent to its defeat at the Baghuz confrontation in the year 2019, the MoD reported.
"I must thank every member of our armed forces involved in this mission for their skill and their courage," Healey added. "Including them were numerous British personnel on duty over Christmas and New Year. This action, to take out militants who pose a risk to our safety, shows how UK forces are always on standby, throughout the year, protecting the UK at home and powerful internationally."
During December, the American forces carried out what it described as a "massive strike" on Islamic State objectives in the country, following an attack killed two US servicemembers and a civilian interpreter in the Palmyra area.
The UN says Daesh still maintains roughly 5-7 thousand combatants in Syria and Iraq.
