British Air Force Typhoon FGR4s have joined forces with France's air force in a joint strike targeting an subterranean weapons facility in Syrian territory operated by the Daesh militant organization, per a report from the British defence ministry.
The location, located using reconnaissance, was believed to be housing weapons and explosive materials, the statement said, and was located in hills just north of the historic site of Palmyra in Syria's central region.
"The RAF jets used precision-guided Paveway IV munitions to target a number of approach shafts leading to the site... initial indications are that the strike was effective," the MoD said.
There was no sign of any harm to civilians in the strike late on Saturday and all the aircraft returned to base without incident, the defence officials confirmed.
The British jets were assisted by a Voyager aerial refuelling aircraft.
The Islamic State group - also known as the so-called Islamic State - established militant control over large swathes of Syria and Iraq prior to its 2019 collapse.
"This strike demonstrates British leadership, and resolve to work closely with allied nations, to stamp out any revival of IS and their dangerous and violent ideologies in the area," UK Defence Secretary the Defence Secretary said.
UK warplanes have carried out patrols over Syria to "prevent any attempted resurgence" of the group subsequent to its defeat at the climactic battle in Baghuz in 2019, the authorities noted.
"I want to thank every member of British forces involved in this operation for their expertise and their bravery," he added. "Including them were numerous British troops stationed over the holidays. This action, to take out dangerous terrorists who endanger our security, shows how British military are prepared to act, throughout the year, ensuring Britain's security domestically and powerful internationally."
Last December, the US military executed what it described as a "major assault" targeting IS targets in Syria, after an attack claimed the lives of two US servicemembers and a civilian linguist in Palmyra.
The UN estimates Islamic State still maintains between 5,000 and 7,000 combatants in both countries.
