British Air Force Typhoon FGR4s have conducted a mission with French warplanes in a coordinated attack on an hidden munitions depot in Syria used by the Daesh militant organization, per a report from the UK Ministry of Defence.
The site, identified by reconnaissance, was assessed as storing arms and explosives, the statement said, and was positioned in hills just to the north of the historic site of Palmyra in Syria's central region.
"The RAF jets utilized precision-guided Paveway IV munitions to hit a several entry passages providing entry to the depot... preliminary assessments are that the objective was successfully hit," the MoD said.
There was no indication of any civilian casualties in the attack on Saturday evening and all the aircraft returned to base without incident, the defence officials confirmed.
The British jets were backed up by a Voyager aerial refuelling aircraft.
The Islamic State group - alternatively referred to as Daesh - enforced extremist governance over parts of Iraq and Syria prior to its 2019 collapse.
"This strike underscores British leadership, and commitment to operate in unison with allied nations, to eliminate any re-emergence of the terrorist group and their harmful and extremist ideologies in the region," Britain's Defence Chief the minister stated.
RAF aircraft have conducted patrols over Syrian airspace to "prevent any attempted resurgence" of Islamic State subsequent to its military defeat at the Baghuz confrontation in 2019, the MoD reported.
"I must thank all the members of our armed forces involved in this strike for their professionalism and their bravery," the Defence Secretary added. "Including them were a great many British personnel deployed over Christmas and New Year. This mission, to remove terrorist threats who pose a risk to our safety, shows how British military are prepared to act, throughout the year, ensuring Britain's security within its borders and powerful internationally."
In December, the United States armed forces conducted what it called a "large-scale strike" on IS targets in the country, following an ambush resulted in the deaths of two American soldiers and a civilian linguist in Palmyra.
The United Nations estimates Islamic State still has between 5,000 and 7,000 militants in Iraq and Syria.
