British Air Force Typhoon fighter aircraft have joined forces with French warplanes in a joint strike against an subterranean weapons facility in Syria used by the IS group, per a report from the British defence ministry.
The location, identified by surveillance, was believed to be containing munitions and bombs, the announcement noted, and was located in mountainous terrain just above Palmyra in the heart of Syria.
"Our aircraft used precision-guided Paveway IV munitions to target a several entry passages down to the facility... initial indications are that the strike was effective," officials stated.
There was no sign of any civilian impact in the operation late on Saturday and each participating jet made a safe return, the MoD added.
The Typhoon FGR4s were assisted by a Voyager refuelling tanker.
The Islamic State group - alternatively referred to as the so-called Islamic State - established militant control over large swathes of Syria and Iraq prior to its 2019 collapse.
"This action shows British leadership, and determination to operate in unison with allied nations, to stamp out any revival of the terrorist group and their harmful and extremist ideologies in the region," the British Defence Secretary the minister said.
British military aircraft have performed surveillance missions over Syrian airspace to "prevent any efforts to regroup" of Islamic State following its routing at the battle of Baghuz in 2019, the authorities noted.
"I extend gratitude to the personnel of the UK armed forces who took part in this mission for their skill and their valour," the Defence Secretary said. "They were among thousands of British personnel deployed over Christmas and New Year. This action, to eliminate militants who threaten our way of life, highlights how UK forces are prepared to act, continuously, keeping Britain secure domestically and influential overseas."
