British Air Force Typhoon FGR4s have operated alongside France's air force in a combined operation against an underground arms cache in Syria employed by the Daesh militant organization, as stated by the British defence ministry.
The site, pinpointed through intelligence, was thought to be containing munitions and bombs, the announcement noted, and was located in mountainous terrain just above Palmyra in the heart of Syria.
"Our fighter planes utilized laser-guided Paveway IV weapons to target a several access tunnels leading to the facility... early reports indicate the objective was successfully hit," the MoD said.
There was no sign of any civilian impact in the strike conducted Saturday night and each participating jet made a safe return, the ministry further stated.
The British jets were assisted by a Voyager aerial refuelling aircraft.
IS - referred to as ISIS - imposed extremist governance over significant areas in both Syria and Iraq before its territorial defeat in 2019.
"This operation shows the UK's leading role, and determination to work closely with allied nations, to eradicate any resurgence of Daesh and their harmful and extremist ideologies in the area," the British Defence Secretary the minister said.
UK warplanes have performed surveillance missions over Syrian airspace to "prevent any efforts to regroup" of the group after its defeat at the climactic battle in Baghuz in the year 2019, the authorities noted.
"I extend gratitude to every member of our armed forces participating in this mission for their expertise and their bravery," Healey added. "Including them were a great many British troops on duty over the festive period. This action, to take out dangerous terrorists who pose a risk to our security, shows how British military are prepared to act, throughout the year, keeping Britain secure domestically and strong abroad."
In December, the United States armed forces carried out what it called a "large-scale strike" on IS targets in Syria, after an attack claimed the lives of two US servicemembers and a civilian interpreter in Palmyra.
The UN reports Daesh still has roughly 5-7 thousand fighters in Syria and Iraq.
