RAF Typhoon FGR4s have conducted a mission with French warplanes in a joint strike targeting an hidden munitions depot in Syrian territory operated by the Islamic State group (IS), per a report from the UK Ministry of Defence.
The location, identified by reconnaissance, was believed to be storing arms and explosives, the statement said, and was positioned in mountainous terrain just above Palmyra in central Syria.
"Our aircraft utilized laser-guided Paveway IV weapons to strike a number of access tunnels down to the site... initial indications indicate the objective was successfully hit," the ministry announced.
There was no evidence of any harm to civilians in the attack on Saturday evening and each participating jet returned to base without incident, the MoD added.
The British jets were supported by a Voyager aerial refuelling aircraft.
IS - also known as ISIS - established jihadist rule over large swathes of Syria and Iraq before its territorial defeat in 2019.
"This action shows our UK leadership, and resolve to stand shoulder to shoulder with our partners, to eradicate any revival of Daesh and their harmful and extremist ideologies in the region," the British Defence Secretary the Defence Secretary stated.
British military aircraft have conducted surveillance missions over Syria to "forestall any attempted resurgence" of the group following its defeat at the Baghuz confrontation in 2019, the ministry said.
"I must thank all the members of the UK armed forces participating in this operation for their skill and their courage," he added. "They were among a great many British personnel on duty over the festive period. This action, to remove militants who threaten our way of life, shows how British military are prepared to act, all year round, keeping Britain secure domestically and powerful internationally."
In December, the United States armed forces carried out what it termed a "major assault" against IS targets in Syria, subsequent to an ambush claimed the lives of two American soldiers and a civilian linguist in the Palmyra area.
The U.N. estimates Daesh still maintains an estimated 5,000 to 7,000 militants in Iraq and Syria.
