RAF Typhoon jets have joined forces with French warplanes in a combined operation on an hidden munitions depot in Syria used by the Daesh militant organization, per a report from the UK Ministry of Defence.
The location, located using reconnaissance, was thought to be housing weapons and explosive materials, the statement said, and was located in hills just above the ancient city of Palmyra in the heart of Syria.
"Our fighter planes utilized Paveway IV guided bombs to target a several entry passages down to the facility... preliminary assessments indicate the objective was successfully hit," the MoD said.
There was no sign of any civilian impact in the attack on Saturday evening and every plane involved returned to base without incident, the defence officials confirmed.
The British jets were assisted by a Voyager aerial refuelling aircraft.
The Islamic State group - referred to as the so-called Islamic State - imposed jihadist rule over parts of Syria and Iraq before its territorial defeat in 2019.
"This operation shows our UK leadership, and determination to operate in unison with our allies, to eradicate any revival of IS and their violent and radical beliefs in the region," Britain's Defence Chief John Healey remarked.
RAF aircraft have carried out overwatch operations over Syrian airspace to "forestall any efforts to regroup" of Islamic State following its routing at the battle of Baghuz in 2019, the ministry said.
"I want to thank all the members of our armed forces who took part in this strike for their skill and their valour," the Defence Secretary added. "They were among thousands of UK service members stationed over the holidays. This action, to remove militants who threaten our security, shows how British military are always on standby, throughout the year, keeping Britain secure within its borders and influential overseas."
Last December, the US military carried out what it termed a "massive strike" on Islamic State objectives in the country, following an attack resulted in the deaths of two US servicemembers and a civilian interpreter in the Palmyra area.
The United Nations reports Islamic State still has between 5,000 and 7,000 militants in Syria and Iraq.
