British Air Force Typhoon FGR4s have joined forces with French warplanes in a coordinated attack against an hidden munitions depot in Syrian territory employed by the IS group, per a report from the UK's MoD.
The site, identified by surveillance, was thought to be storing arms and explosives, the announcement noted, and was situated in hills just to the north of the ancient city of Palmyra in Syria's central region.
"The RAF jets utilized Paveway IV guided bombs to hit a number of entry passages down to the facility... early reports suggest the target was engaged successfully," the MoD said.
There was no sign of any civilian casualties in the operation late on Saturday and each participating jet returned safely, the ministry further stated.
The Typhoon fighters were supported by a Voyager aerial refuelling aircraft.
IS - alternatively referred to as ISIS - established jihadist rule over significant areas in Iraq and Syria before its territorial defeat in 2019.
"This action demonstrates British leadership, and commitment to operate in unison with our allies, to eradicate any resurgence of Daesh and their harmful and extremist ideologies in the area," UK Defence Secretary John Healey remarked.
British military aircraft have carried out surveillance missions over Syria to "prevent any attempted comeback" of Islamic State after its military defeat at the climactic battle in Baghuz in the year 2019, the ministry said.
"I must thank the personnel of our armed forces involved in this operation for their skill and their courage," the Defence Secretary commented. "Including them were numerous UK service members on duty over the holidays. This action, to eliminate terrorist threats who endanger our security, shows how British military are always on standby, continuously, ensuring Britain's security domestically and strong abroad."
In December, the United States armed forces carried out what it called a "large-scale strike" on IS targets in the country, after an ambush claimed the lives of two US troops and a local interpreter in Palmyra.
The UN reports Islamic State still boasts an estimated 5,000 to 7,000 militants in Iraq and Syria.
