Royal Air Force Typhoon jets have operated alongside France's air force in a coordinated attack on an hidden munitions depot in Syrian territory employed by the IS group, as stated by the British defence ministry.
The site, identified by surveillance, was assessed as storing arms and explosives, the statement said, and was situated in hills just above the ancient city of Palmyra in central Syria.
"The RAF jets used Paveway IV guided bombs to strike a several entry passages providing entry to the facility... initial indications indicate the objective was successfully hit," officials stated.
There was no sign of any civilian casualties in the operation late on Saturday and every plane involved made a safe return, the defence officials confirmed.
The Typhoon FGR4s were assisted by a Voyager tanker plane.
Daesh - referred to as the so-called Islamic State - established extremist governance over significant areas in both Syria and Iraq prior to its 2019 collapse.
"This action shows British leadership, and commitment to stand shoulder to shoulder with our partners, to stamp out any resurgence of IS and their violent and radical beliefs in the region," UK Defence Secretary the minister stated.
British military aircraft have performed patrols over Syria to "deter any attempted comeback" of the group following its routing at the battle of Baghuz in 2019, the MoD reported.
"I want to thank the personnel of the UK armed forces involved in this mission for their expertise and their valour," Healey added. "They were among numerous British personnel on duty over Christmas and New Year. This action, to take out dangerous terrorists who endanger our way of life, demonstrates how British military are prepared to act, continuously, keeping Britain secure at home and influential overseas."
Last December, the United States armed forces executed what it termed a "massive strike" on Daesh sites in the country, following an attack resulted in the deaths of two US servicemembers and a local interpreter in the Palmyra area.
The UN reports Daesh still has roughly 5-7 thousand fighters in Syria and Iraq.
