British Air Force Typhoon FGR4s have operated alongside French warplanes in a combined operation on an hidden munitions depot in Syria used by the Daesh militant organization, per a report from the British defence ministry.
The site, identified by surveillance, was assessed as containing munitions and bombs, the release indicated, and was located in hills just north of the historic site of Palmyra in the heart of Syria.
"Our fighter planes used Paveway IV guided bombs to target a series of access tunnels down to the facility... initial indications indicate the target was engaged successfully," the MoD said.
There was no indication of any civilian casualties in the operation on Saturday evening and each participating jet returned safely, the MoD added.
The Typhoon FGR4s were supported by a Voyager aerial refuelling aircraft.
Daesh - also known as ISIS - enforced jihadist rule over large swathes of Syria and Iraq until 2019.
"This strike shows the UK's leading role, and determination to work closely with our allies, to eradicate any resurgence of the terrorist group and their harmful and extremist ideologies in the Middle East," the British Defence Secretary the Defence Secretary said.
British military aircraft have conducted patrols over Syria to "prevent any attempted comeback" of the group after its defeat at the climactic battle in Baghuz in 2019, the MoD reported.
"I want to thank the personnel of the UK armed forces involved in this strike for their expertise and their valour," the Defence Secretary commented. "They were among numerous British troops on duty over the holidays. This operation, to eliminate terrorist threats who endanger our way of life, shows how UK forces are always on standby, all year round, ensuring Britain's security at home and powerful internationally."
In December, the American forces carried out what it termed a "large-scale strike" on Islamic State objectives in Syria, after an assault claimed the lives of two US servicemembers and a local interpreter in the Palmyra area.
The UN estimates Islamic State still has an estimated 5,000 to 7,000 fighters in both countries.
