RAF Typhoon fighter aircraft have conducted a mission with French warplanes in a joint strike against an hidden munitions depot in Syrian territory used by the IS group, as stated by the UK's MoD.
The location, pinpointed through intelligence, was assessed as containing munitions and bombs, the statement said, and was located in mountainous terrain just above Palmyra in the heart of Syria.
"The RAF jets employed laser-guided Paveway IV weapons to strike a series of entry passages down to the depot... preliminary assessments suggest the target was engaged successfully," officials stated.
There was no indication of any civilian impact in the attack on Saturday evening and all the aircraft made a safe return, the defence officials confirmed.
The British jets were supported by a Voyager tanker plane.
IS - also known as the so-called Islamic State - established jihadist rule over large swathes of both Syria and Iraq until 2019.
"This operation demonstrates our UK leadership, and resolve to work closely with our allies, to eradicate any resurgence of Daesh and their dangerous and violent ideologies in the Middle East," Britain's Defence Chief the minister said.
RAF aircraft have conducted overwatch operations over Syrian airspace to "forestall any efforts to regroup" of IS after its defeat at the Baghuz confrontation in the year 2019, the MoD reported.
"I want to thank the personnel of the UK armed forces involved in this mission for their skill and their courage," the Defence Secretary added. "Including them were thousands of British personnel on duty over the holidays. This operation, to take out dangerous terrorists who pose a risk to our safety, shows how British military are always on standby, continuously, ensuring Britain's security at home and influential overseas."
During December, the United States armed forces carried out what it described as a "major assault" against Daesh sites in the country, following an attack killed two US troops and a civilian linguist in the Palmyra area.
The United Nations reports Islamic State still boasts roughly 5-7 thousand fighters in Iraq and Syria.
