Royal Air Force Typhoon FGR4s have conducted a mission with French aircraft in a combined operation against an underground arms cache in Syrian territory operated by the IS group, as stated by the UK Ministry of Defence.
The location, located using intelligence, was believed to be containing munitions and bombs, the release indicated, and was situated in hills just above Palmyra in Syria's central region.
"The RAF jets employed Paveway IV guided bombs to hit a several entry passages providing entry to the depot... early reports suggest the target was engaged successfully," the ministry announced.
There was no indication of any civilian impact in the operation on Saturday evening and each participating jet made a safe return, the ministry further stated.
The Typhoon FGR4s were backed up by a Voyager aerial refuelling aircraft.
IS - referred to as ISIS - established extremist governance over large swathes of Syria and Iraq prior to its 2019 collapse.
"This strike demonstrates British leadership, and resolve to work closely with our partners, to stamp out any resurgence of Daesh and their dangerous and violent ideologies in the region," Britain's Defence Chief the minister stated.
RAF aircraft have conducted overwatch operations over Syria to "prevent any attempted resurgence" of IS subsequent to its defeat at the climactic battle in Baghuz in 2019, the authorities noted.
"I extend gratitude to all the members of our armed forces involved in this strike for their professionalism and their bravery," Healey added. "They were part of a great many British troops stationed over the holidays. This action, to remove dangerous terrorists who threaten our security, highlights how our armed forces are always on standby, throughout the year, keeping Britain secure at home and influential overseas."
Last December, the American forces carried out what it called a "massive strike" targeting Daesh sites in the country, following an assault killed two US troops and a local interpreter in Palmyra.
The U.N. reports Islamic State still has an estimated 5,000 to 7,000 militants in Iraq and Syria.
