RAF Typhoon FGR4s have operated alongside France's air force in a coordinated attack targeting an hidden munitions depot in Syria used by the Daesh militant organization, as stated by the UK Ministry of Defence.
The site, located using surveillance, was assessed as containing munitions and bombs, the announcement noted, and was located in mountainous terrain just above Palmyra in Syria's central region.
"The RAF jets employed precision-guided Paveway IV munitions to hit a number of approach shafts down to the facility... preliminary assessments indicate the strike was effective," the MoD said.
There was no indication of any civilian casualties in the attack conducted Saturday night and all the aircraft returned safely, the ministry further stated.
The Typhoon FGR4s were supported by a Voyager aerial refuelling aircraft.
IS - also known as the so-called Islamic State - established jihadist rule over parts of Syria and Iraq prior to its 2019 collapse.
"This operation underscores British leadership, and resolve to operate in unison with our partners, to eradicate any revival of the terrorist group and their dangerous and violent ideologies in the area," UK Defence Secretary the Defence Secretary said.
British military aircraft have performed patrols over Syria to "forestall any efforts to regroup" of the group after its military defeat at the Baghuz confrontation in the year 2019, the authorities noted.
"I must thank every member of our armed forces who took part in this strike for their expertise and their bravery," he said. "They were part of a great many British personnel stationed over Christmas and New Year. This operation, to take out militants who threaten our safety, demonstrates how our armed forces are always on standby, continuously, keeping Britain secure domestically and strong abroad."
Last December, the US military carried out what it called a "large-scale strike" on Daesh sites in the country, after an attack resulted in the deaths of two US servicemembers and a local interpreter in Palmyra.
The U.N. reports Islamic State still has roughly 5-7 thousand fighters in Iraq and Syria.
