RAF Typhoon fighter aircraft have conducted a mission with French aircraft in a joint strike targeting an hidden munitions depot in Syria operated by the IS group, per a report from the UK Ministry of Defence.
The location, located using reconnaissance, was believed to be storing arms and explosives, the statement said, and was located in hills just above Palmyra in Syria's central region.
"Our aircraft employed Paveway IV guided bombs to target a series of access tunnels leading to the depot... initial indications are that the target was engaged successfully," the MoD said.
There was no evidence of any civilian impact in the strike conducted Saturday night and all the aircraft returned to base without incident, the defence officials confirmed.
The British jets were backed up by a Voyager tanker plane.
The Islamic State group - referred to as the so-called Islamic State - established militant control over large swathes of Syria and Iraq prior to its 2019 collapse.
"This operation demonstrates our UK leadership, and commitment to stand shoulder to shoulder with our partners, to stamp out any revival of the terrorist group and their harmful and extremist ideologies in the Middle East," the British Defence Secretary the Defence Secretary remarked.
UK warplanes have carried out surveillance missions over Syria to "prevent any attempted resurgence" of the group after its routing at the battle of Baghuz in 2019, the authorities noted.
"I want to thank the personnel of the UK armed forces involved in this strike for their expertise and their valour," the Defence Secretary said. "Including them were a great many British personnel deployed over the holidays. This mission, to take out terrorist threats who endanger our security, highlights how UK forces are prepared to act, continuously, protecting the UK within its borders and powerful internationally."
During December, the US military executed what it called a "massive strike" targeting Islamic State objectives in the country, after an ambush resulted in the deaths of two American soldiers and a civilian linguist in Palmyra.
The U.N. reports IS still boasts an estimated 5,000 to 7,000 militants in Iraq and Syria.
