RAF Typhoon jets have conducted a mission with French warplanes in a joint strike against an hidden munitions depot in Syria used by the IS group, according to the UK Ministry of Defence.
The site, located using surveillance, was believed to be housing weapons and explosive materials, the statement said, and was situated in hills just to the north of the historic site of Palmyra in the heart of Syria.
"The RAF jets utilized precision-guided Paveway IV munitions to target a number of approach shafts providing entry to the facility... initial indications indicate the strike was effective," the MoD said.
There was no sign of any civilian casualties in the strike conducted Saturday night and every plane involved returned safely, the defence officials confirmed.
The Typhoon FGR4s were assisted by a Voyager tanker plane.
Daesh - referred to as Daesh - established militant control over large swathes of Syria and Iraq until 2019.
"This action underscores the UK's leading role, and determination to operate in unison with allied nations, to eradicate any revival of the terrorist group and their violent and radical beliefs in the region," the British Defence Secretary the Defence Secretary remarked.
UK warplanes have performed overwatch operations over Syrian airspace to "deter any attempted resurgence" of Islamic State subsequent to its defeat at the Baghuz confrontation in 2019, the MoD reported.
"I extend gratitude to all the members of the UK armed forces who took part in this operation for their professionalism and their bravery," he commented. "Including them were a great many British personnel on duty over Christmas and New Year. This operation, to remove militants who pose a risk to our way of life, shows how UK forces are prepared to act, all year round, protecting the UK within its borders and powerful internationally."
Last December, the United States armed forces executed what it described as a "major assault" targeting Islamic State objectives in the country, after an assault killed two US servicemembers and a civilian interpreter in Palmyra.
The United Nations estimates Islamic State still has between 5,000 and 7,000 combatants in Syria and Iraq.
