Royal Air Force Typhoon fighter aircraft have operated alongside French aircraft in a coordinated attack against an hidden munitions depot in Syria employed by the Daesh militant organization, as stated by the UK Ministry of Defence.
The location, pinpointed through surveillance, was believed to be housing weapons and explosive materials, the announcement noted, and was located in mountainous terrain just to the north of Palmyra in central Syria.
"The RAF jets employed laser-guided Paveway IV weapons to strike a series of access tunnels leading to the site... preliminary assessments indicate the strike was effective," the MoD said.
There was no indication of any harm to civilians in the operation on Saturday evening and each participating jet returned to base without incident, the defence officials confirmed.
The Typhoon fighters were assisted by a Voyager tanker plane.
IS - also known as ISIS - imposed extremist governance over large swathes of both Syria and Iraq before its territorial defeat in 2019.
"This strike underscores British leadership, and commitment to operate in unison with our partners, to eradicate any re-emergence of the terrorist group and their harmful and extremist ideologies in the Middle East," Britain's Defence Chief John Healey said.
British military aircraft have carried out surveillance missions over Syria to "prevent any attempted resurgence" of IS subsequent to its military defeat at the battle of Baghuz in 2019, the ministry said.
"I must thank the personnel of British forces involved in this strike for their professionalism and their valour," the Defence Secretary said. "They were part of numerous British troops stationed over the holidays. This mission, to take out dangerous terrorists who pose a risk to our way of life, demonstrates how British military are always on standby, all year round, ensuring Britain's security within its borders and powerful internationally."
Last December, the American forces conducted what it described as a "major assault" against Daesh sites in Syria, following an attack resulted in the deaths of two US troops and a civilian linguist in Palmyra.
The United Nations reports IS still maintains between 5,000 and 7,000 militants in Iraq and Syria.
