British Air Force Typhoon FGR4s have conducted a mission with French warplanes in a coordinated attack against an underground arms cache in Syria operated by the Islamic State group (IS), per a report from the UK's MoD.
The facility, located using intelligence, was assessed as containing munitions and bombs, the release indicated, and was positioned in hills just north of Palmyra in central Syria.
"Our aircraft used precision-guided Paveway IV munitions to target a series of entry passages down to the depot... preliminary assessments indicate the strike was effective," 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 ministry further stated.
The Typhoon FGR4s were supported by a Voyager aerial refuelling aircraft.
Daesh - alternatively referred to as Daesh - established extremist governance over significant areas in Syria and Iraq until 2019.
"This action shows the UK's leading role, and resolve to stand shoulder to shoulder with our partners, to eliminate any resurgence of IS and their dangerous and violent ideologies in the region," Britain's Defence Chief the minister said.
British military aircraft have performed patrols over Syria to "prevent any attempted resurgence" of Islamic State after its defeat at the climactic battle in 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 expertise and their valour," the Defence Secretary said. "Including them were a great many UK service members stationed over the holidays. This action, to take out terrorist threats who threaten our safety, highlights how our armed forces are always on standby, all year round, ensuring Britain's security at home and strong abroad."
During December, the United States armed forces executed what it described as a "large-scale strike" on Islamic State objectives in the country, following an ambush killed two American soldiers and a local interpreter in the Palmyra area.
The UN says Islamic State still boasts roughly 5-7 thousand combatants in Syria and Iraq.
