British Air Force Typhoon FGR4s have conducted a mission with French warplanes in a combined operation targeting an hidden munitions depot in Syrian territory operated by the Daesh militant organization, as stated by the UK Ministry of Defence.
The location, located using surveillance, was thought to be containing munitions and bombs, the release indicated, and was positioned in hills just to the north of Palmyra in central Syria.
"The RAF jets employed Paveway IV guided bombs to hit a number of entry passages down to the depot... early reports are that the strike was effective," the ministry announced.
There was no evidence of any harm to civilians in the attack late on Saturday and each participating jet returned to base without incident, the MoD added.
The British jets were supported by a Voyager tanker plane.
IS - referred to as the so-called Islamic State - imposed jihadist rule over parts of Syria and Iraq until 2019.
"This operation demonstrates our UK leadership, and determination to work closely with our allies, to stamp out any resurgence of the terrorist group and their violent and radical beliefs in the Middle East," UK Defence Secretary John Healey said.
UK warplanes have carried out surveillance missions over Syrian airspace to "prevent any attempted resurgence" of IS following its military defeat at the climactic battle in Baghuz in 2019, the ministry said.
"I want to thank all the members of British forces who took part in this mission for their skill and their courage," the Defence Secretary commented. "They were among numerous British troops on duty over Christmas and New Year. This action, to take out terrorist threats who threaten our safety, shows how our armed forces are prepared to act, all year round, ensuring Britain's security within its borders and strong abroad."
In December, the US military executed what it called a "large-scale strike" targeting Islamic State objectives in the country, following an attack claimed the lives of two US troops and a civilian interpreter in Palmyra.
The UN reports Daesh still maintains an estimated 5,000 to 7,000 militants in Iraq and Syria.
