British Air Force Typhoon jets have joined forces with French warplanes in a coordinated attack against an hidden munitions depot in Syria used by the IS group, per a report from the British defence ministry.
The location, identified by reconnaissance, was assessed as housing weapons and explosive materials, the announcement noted, and was located in mountainous terrain just above the ancient city of Palmyra in the heart of Syria.
"Our aircraft utilized laser-guided Paveway IV weapons to target a several access tunnels leading to the site... preliminary assessments are that the objective was successfully hit," the MoD said.
There was no evidence of any civilian impact in the operation on Saturday evening and all the aircraft returned safely, the MoD added.
The Typhoon FGR4s were backed up by a Voyager tanker plane.
Daesh - also known as Daesh - enforced jihadist rule over significant areas in both Syria and Iraq prior to its 2019 collapse.
"This operation shows British leadership, and determination to operate in unison with allied nations, to stamp out any resurgence of IS and their harmful and extremist ideologies in the Middle East," UK Defence Secretary the Defence Secretary stated.
British military aircraft have carried out patrols over Syria to "prevent any attempted comeback" of Islamic State after its routing at the climactic battle in Baghuz in 2019, the MoD reported.
"I want to thank all the members of our armed forces involved in this strike for their skill and their courage," Healey added. "They were among a great many British troops stationed over Christmas and New Year. This operation, to eliminate terrorist threats who endanger our security, highlights how UK forces are always on standby, all year round, keeping Britain secure within its borders and influential overseas."
In December, the American forces conducted what it described as a "massive strike" targeting Islamic State objectives in the country, subsequent to an assault killed two US servicemembers and a civilian interpreter in the Palmyra area.
The United Nations reports Daesh still has an estimated 5,000 to 7,000 combatants in both countries.
