British Air Force Typhoon FGR4s have joined forces with France's air force in a combined operation on an underground arms cache in Syria employed by the IS group, per a report from the British defence ministry.
The location, pinpointed through reconnaissance, was believed to be storing arms and explosives, the statement said, and was located in hills just north of the historic site of Palmyra in Syria's central region.
"Our aircraft employed precision-guided Paveway IV munitions to strike a number of approach shafts down to the depot... preliminary assessments are that the objective was successfully hit," the ministry announced.
There was no indication of any harm to civilians in the strike conducted Saturday night and every plane involved 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 - also known as the so-called Islamic State - enforced extremist governance over significant areas in Iraq and Syria before its territorial defeat in 2019.
"This action demonstrates our UK leadership, and determination to work closely with allied nations, to stamp out any resurgence of Daesh and their violent and radical beliefs in the area," UK Defence Secretary the minister said.
British military aircraft have carried out surveillance missions over Syria to "prevent any efforts to regroup" of the group following its defeat at the battle of Baghuz in the year 2019, the ministry said.
"I want to thank the personnel of our armed forces who took part in this strike for their expertise and their courage," the Defence Secretary said. "They were among a great many British troops on duty over the holidays. This action, to take out terrorist threats who pose a risk to our way of life, shows how UK forces are always on standby, all year round, ensuring Britain's security within its borders and influential overseas."
Last December, the American forces conducted what it termed a "major assault" targeting Islamic State objectives in Syria, following an ambush killed two American soldiers and a local interpreter in the Palmyra area.
The UN reports IS still has between 5,000 and 7,000 fighters in Syria and Iraq.
