British Air Force Typhoon FGR4s have operated alongside French aircraft in a joint strike on an hidden munitions depot in Syrian territory used by the Islamic State group (IS), per a report from the UK's MoD.
The location, located using intelligence, was thought to be storing arms and explosives, the statement said, and was situated in mountainous terrain just to the north of Palmyra in the heart of Syria.
"Our fighter planes utilized Paveway IV guided bombs to strike a series of entry passages leading to the site... early reports suggest the objective was successfully hit," officials stated.
There was no indication of any harm to civilians in the strike late on Saturday and all the aircraft returned to base without incident, the ministry further stated.
The British jets were supported by a Voyager aerial refuelling aircraft.
Daesh - alternatively referred to as ISIS - imposed jihadist rule over parts of Iraq and Syria before its territorial defeat in 2019.
"This action underscores our UK leadership, and resolve to operate in unison with our partners, to stamp out any revival of IS and their dangerous and violent ideologies in the region," Britain's Defence Chief John Healey stated.
RAF aircraft have performed overwatch operations over Syria to "forestall any attempted comeback" of Islamic State after its defeat at the Baghuz confrontation in 2019, the MoD reported.
"I extend gratitude to the personnel of the UK armed forces participating in this strike for their skill and their valour," the Defence Secretary added. "Including them were numerous UK service members on duty over the festive period. This action, to take out terrorist threats who endanger our security, highlights how British military are prepared to act, continuously, ensuring Britain's security at home and influential overseas."
During December, the American forces carried out what it termed a "massive strike" targeting IS targets in the country, subsequent to an assault resulted in the deaths of two US servicemembers and a civilian interpreter in the Palmyra area.
The United Nations estimates IS still has an estimated 5,000 to 7,000 militants in Iraq and Syria.
