British Air Force Typhoon jets have joined forces with French warplanes in a combined operation against an underground arms cache in Syria operated by the Islamic State group (IS), as stated by the UK Ministry of Defence.
The location, located using surveillance, was assessed as containing munitions and bombs, the statement said, and was located in hills just above the historic site of Palmyra in the heart of Syria.
"Our aircraft used precision-guided Paveway IV munitions to target a number of approach shafts down to the facility... preliminary assessments suggest the objective was successfully hit," officials stated.
There was no indication of any civilian impact in the strike on Saturday evening and all the aircraft returned to base without incident, the MoD added.
The Typhoon FGR4s were assisted by a Voyager tanker plane.
Daesh - referred to as Daesh - established extremist governance over large swathes of Syria and Iraq prior to its 2019 collapse.
"This action shows British leadership, and resolve to stand shoulder to shoulder with our partners, to eradicate any re-emergence of the terrorist group and their dangerous and violent ideologies in the region," Britain's Defence Chief John Healey said.
UK warplanes have performed patrols over Syria to "forestall any attempted resurgence" of the group following its military defeat at the Baghuz confrontation in the year 2019, the ministry said.
"I must thank every member of British forces involved in this mission for their expertise and their courage," Healey added. "They were among thousands of UK service members on duty over Christmas and New Year. This mission, to take out dangerous terrorists who threaten our security, shows how UK forces are always on standby, continuously, keeping Britain secure domestically and strong abroad."
During December, the United States armed forces conducted what it described as a "major assault" against Daesh sites in the country, following an ambush resulted in the deaths of two US troops and a civilian linguist in Palmyra.
The UN says Daesh still maintains between 5,000 and 7,000 fighters in Iraq and Syria.
