RAF Typhoon FGR4s have joined forces with French warplanes in a joint strike targeting an hidden munitions depot in Syria used by the Islamic State group (IS), as stated by the British defence ministry.
The site, pinpointed through intelligence, was thought to be storing arms and explosives, the statement said, and was located in mountainous terrain just to the north of the historic site of Palmyra in Syria's central region.
"Our aircraft used precision-guided Paveway IV munitions to target a several access tunnels leading to the facility... early reports are that the strike was effective," the MoD said.
There was no sign of any civilian casualties in the operation on Saturday evening and all the aircraft made a safe return, the defence officials confirmed.
The British jets were supported by a Voyager aerial refuelling aircraft.
The Islamic State group - alternatively referred to as the so-called Islamic State - enforced extremist governance over parts of Iraq and Syria until 2019.
"This operation shows British leadership, and commitment to stand shoulder to shoulder with allied nations, to eradicate any revival of Daesh and their dangerous and violent ideologies in the Middle East," Britain's Defence Chief the Defence Secretary remarked.
UK warplanes have performed patrols over Syria to "prevent any attempted comeback" of Islamic State following its defeat at the Baghuz confrontation in 2019, the ministry said.
"I want to thank all the members of British forces involved in this strike for their skill and their bravery," the Defence Secretary added. "They were among thousands of British troops stationed over the holidays. This operation, to eliminate dangerous terrorists who threaten our security, shows how our armed forces are ready to step up, continuously, protecting the UK domestically and influential overseas."
In December, the US military conducted what it described as a "major assault" targeting Daesh sites in Syria, after an attack resulted in the deaths of two American soldiers and a civilian linguist in the Palmyra area.
The UN says Daesh still maintains an estimated 5,000 to 7,000 combatants in Iraq and Syria.
