British Air Force Typhoon FGR4s have operated alongside French warplanes in a coordinated attack targeting an hidden munitions depot in Syria operated by the IS group, per a report from the British defence ministry.
The site, pinpointed through intelligence, was assessed as containing munitions and bombs, the statement said, and was positioned in mountainous terrain just to the north of the historic site of Palmyra in central Syria.
"Our fighter planes utilized Paveway IV guided bombs to strike a several approach shafts down to the depot... early reports suggest the objective was successfully hit," the MoD said.
There was no sign of any civilian casualties in the strike late on Saturday and every plane involved returned to base without incident, the ministry further stated.
The Typhoon FGR4s were assisted by a Voyager tanker plane.
The Islamic State group - also known as the so-called Islamic State - established extremist governance over parts of Syria and Iraq prior to its 2019 collapse.
"This operation shows British leadership, and resolve to work closely with our allies, to eradicate any re-emergence of Daesh and their harmful and extremist ideologies in the area," Britain's Defence Chief the Defence Secretary remarked.
UK warplanes have conducted surveillance missions over Syrian airspace to "prevent any efforts to regroup" of Islamic State following its defeat at the battle of Baghuz in 2019, the ministry said.
"I must thank the personnel of our armed forces participating in this mission for their expertise and their valour," the Defence Secretary added. "They were among thousands of British troops stationed over the festive period. This mission, to remove militants who pose a risk to our way of life, demonstrates how UK forces are ready to step up, all year round, ensuring Britain's security within its borders and influential overseas."
In December, the US military conducted what it described as a "massive strike" targeting Islamic State objectives in Syria, subsequent to an assault claimed the lives of two US servicemembers and a civilian interpreter in Palmyra.
The U.N. reports Daesh still has between 5,000 and 7,000 militants in Syria and Iraq.
