Royal Air Force Typhoon jets have operated alongside French warplanes in a combined operation targeting an underground arms cache in Syrian territory used by the Daesh militant organization, according to the UK Ministry of Defence.
The location, identified by surveillance, was believed to be housing weapons and explosive materials, the release indicated, and was located in mountainous terrain just above Palmyra in central Syria.
"Our fighter planes used precision-guided Paveway IV munitions to hit a several entry passages leading to the facility... preliminary assessments indicate the target was engaged successfully," the MoD said.
There was no indication of any civilian casualties in the attack late on Saturday and every plane involved returned to base without incident, the MoD added.
The Typhoon fighters were backed up by a Voyager aerial refuelling aircraft.
IS - alternatively referred to as ISIS - established jihadist rule over significant areas in Iraq and Syria until 2019.
"This strike demonstrates British leadership, and resolve to work closely with our partners, to eradicate any revival of Daesh and their harmful and extremist ideologies in the area," Britain's Defence Chief John Healey stated.
RAF aircraft have conducted patrols over Syria to "forestall any attempted comeback" of IS following its military defeat at the climactic battle in Baghuz in the year 2019, the authorities noted.
"I want to thank every member of British forces involved in this strike for their professionalism and their courage," Healey commented. "They were among numerous British personnel on duty over the holidays. This operation, to eliminate terrorist threats who endanger our way of life, demonstrates how British military are always on standby, continuously, protecting the UK at home and powerful internationally."
Last December, the American forces executed what it termed a "major assault" against Islamic State objectives in Syria, after an attack claimed the lives of two American soldiers and a local interpreter in the Palmyra area.
The United Nations says Daesh still boasts roughly 5-7 thousand fighters in Syria and Iraq.
