British Air Force Typhoon FGR4s have conducted a mission with French aircraft in a combined operation on an subterranean weapons facility in Syria used by the IS group, according to the UK Ministry of Defence.
The location, pinpointed through surveillance, was thought to be housing weapons and explosive materials, the statement said, and was situated in mountainous terrain just north of the ancient city of Palmyra in central Syria.
"Our fighter planes utilized precision-guided Paveway IV munitions to target a series of entry passages leading to the site... early reports are that the target was engaged successfully," the ministry announced.
There was no indication of any civilian impact in the strike late on Saturday and every plane involved returned to base without incident, the defence officials confirmed.
The Typhoon FGR4s were assisted by a Voyager aerial refuelling aircraft.
Daesh - also known as Daesh - established jihadist rule over large swathes of Syria and Iraq before its territorial defeat in 2019.
"This operation shows the UK's leading role, and determination to operate in unison with allied nations, to eradicate any revival of Daesh and their violent and radical beliefs in the Middle East," Britain's Defence Chief the Defence Secretary remarked.
British military aircraft have performed overwatch operations over Syria to "forestall any efforts to regroup" of the group subsequent to its routing at the climactic battle in Baghuz in 2019, the authorities noted.
"I extend gratitude to every member of our armed forces who took part in this operation for their professionalism and their courage," he commented. "They were part of numerous British personnel on duty over the holidays. This action, to take out dangerous terrorists who endanger our way of life, demonstrates how British military are prepared to act, continuously, protecting the UK within its borders and strong abroad."
During December, the American forces carried out what it described as a "massive strike" against Islamic State objectives in the country, following an ambush claimed the lives of two American soldiers and a civilian linguist in the Palmyra area.
The United Nations reports Daesh still has between 5,000 and 7,000 combatants in Iraq and Syria.
