British Air Force Typhoon jets have operated alongside France's air force in a coordinated attack targeting an hidden munitions depot in Syria employed by the Islamic State group (IS), per a report from the UK Ministry of Defence.
The facility, identified by reconnaissance, was believed to be storing arms and explosives, the announcement noted, and was positioned in hills just above Palmyra in the heart of Syria.
"Our aircraft employed precision-guided Paveway IV munitions to hit a series of access tunnels leading to the depot... early reports indicate the target was engaged successfully," the MoD said.
There was no evidence of any civilian impact in the strike late on Saturday and every plane involved returned safely, the ministry further stated.
The Typhoon FGR4s were backed up by a Voyager refuelling tanker.
The Islamic State group - referred to as ISIS - established extremist governance over parts of Iraq and Syria until 2019.
"This operation underscores our UK leadership, and commitment to stand shoulder to shoulder with our partners, to eradicate any re-emergence of Daesh and their harmful and extremist ideologies in the region," Britain's Defence Chief John Healey remarked.
RAF aircraft have carried out surveillance missions over Syrian airspace to "prevent any attempted comeback" of Islamic State after its routing at the battle of Baghuz in 2019, the ministry said.
"I extend gratitude to the personnel of British forces who took part in this strike for their professionalism and their bravery," Healey added. "Including them were thousands of British personnel on duty over the festive period. This operation, to take out terrorist threats who endanger our safety, shows how UK forces are prepared to act, continuously, protecting the UK within its borders and powerful internationally."
Last December, the United States armed forces executed what it described as a "large-scale strike" on IS targets in Syria, following an assault killed two American soldiers and a civilian interpreter in the Palmyra area.
The UN says Daesh still boasts roughly 5-7 thousand militants in Iraq and Syria.
