Royal Air Force Typhoon FGR4s have joined forces with French aircraft in a coordinated attack targeting an hidden munitions depot in Syria used by the IS group, as stated by the UK Ministry of Defence.
The location, pinpointed through intelligence, was believed to be housing weapons and explosive materials, the release indicated, and was positioned in mountains just to the north of Palmyra in Syria's central region.
"Our fighter planes employed precision-guided Paveway IV munitions to target a several approach shafts down to the site... early reports indicate the strike was effective," the ministry announced.
There was no sign of any civilian impact in the attack on Saturday evening and every plane involved returned safely, the defence officials confirmed.
The Typhoon fighters were backed up by a Voyager tanker plane.
IS - referred to as ISIS - imposed extremist governance over significant areas in both Syria and Iraq until 2019.
"This action demonstrates British leadership, and commitment to operate in unison with allied nations, to eradicate any resurgence of the terrorist group and their dangerous and violent ideologies in the area," Britain's Defence Chief the minister said.
UK warplanes have conducted patrols over Syrian airspace to "prevent any efforts to regroup" of Islamic State after its routing at the climactic battle in Baghuz in 2019, the MoD reported.
"I want to thank the personnel of the UK armed forces who took part in this mission for their professionalism and their bravery," Healey commented. "They were among a great many UK service members on duty over the festive period. This action, to eliminate terrorist threats who pose a risk to our way of life, shows how our armed forces are always on standby, all year round, ensuring Britain's security at home and strong abroad."
Last December, the US military conducted what it termed a "large-scale strike" targeting Islamic State objectives in Syria, subsequent to an ambush killed two American soldiers and a local interpreter in the Palmyra area.
The UN estimates Islamic State still boasts roughly 5-7 thousand militants in Iraq and Syria.
