RAF Typhoon FGR4s have operated alongside French aircraft in a joint strike on an underground arms cache in Syrian territory used by the Daesh militant organization, per a report from the UK Ministry of Defence.
The location, located using intelligence, was assessed as housing weapons and explosive materials, the announcement noted, and was positioned in hills just to the north of Palmyra in central Syria.
"Our aircraft utilized laser-guided Paveway IV weapons to strike a number of approach shafts down to the facility... initial indications suggest the target was engaged successfully," the MoD said.
There was no evidence of any civilian casualties in the attack conducted Saturday night and all the aircraft returned to base without incident, the defence officials confirmed.
The British jets were assisted by a Voyager tanker plane.
Daesh - alternatively referred to as ISIS - established extremist governance over parts of Syria and Iraq before its territorial defeat in 2019.
"This operation demonstrates British leadership, and determination to operate in unison with our partners, to stamp out any revival of IS and their dangerous and violent ideologies in the region," UK Defence Secretary the minister stated.
UK warplanes have conducted surveillance missions over Syrian airspace to "prevent any attempted comeback" of Islamic State following its defeat at the climactic battle in Baghuz in 2019, the ministry said.
"I extend gratitude to the personnel of British forces involved in this operation for their expertise and their valour," he added. "They were part of numerous British personnel stationed over Christmas and New Year. This action, to eliminate dangerous terrorists who pose a risk to our security, demonstrates how British military are prepared to act, all year round, protecting the UK domestically and influential overseas."
Last December, the American forces executed what it described as a "massive strike" targeting Islamic State objectives in the country, subsequent to an ambush killed two American soldiers and a civilian interpreter in the Palmyra area.
The U.N. says IS still has between 5,000 and 7,000 combatants in Iraq and Syria.
