Royal Air Force Typhoon FGR4s have joined forces with French warplanes in a joint strike against an underground arms cache in Syria used by the IS group, as stated by the UK Ministry of Defence.
The site, identified by surveillance, was believed to be containing munitions and bombs, the announcement noted, and was located in hills just above Palmyra in central Syria.
"The RAF jets used Paveway IV guided bombs to hit a number of entry passages providing entry to the facility... early reports are that the target was engaged successfully," the MoD said.
There was no evidence of any civilian impact in the attack late on Saturday and each participating jet returned safely, the MoD added.
The Typhoon FGR4s were supported by a Voyager aerial refuelling aircraft.
IS - alternatively referred to as the so-called Islamic State - established jihadist rule over parts of Syria and Iraq before its territorial defeat in 2019.
"This action shows our UK leadership, and resolve to work closely with allied nations, to eradicate any revival of Daesh and their dangerous and violent ideologies in the Middle East," the British Defence Secretary the minister said.
RAF aircraft have performed overwatch operations over Syrian airspace to "deter any attempted resurgence" of IS subsequent to its defeat at the climactic battle in Baghuz in 2019, the ministry said.
"I want to thank the personnel of British forces who took part in this strike for their expertise and their valour," Healey commented. "They were part of a great many British personnel on duty over Christmas and New Year. This operation, to remove terrorist threats who threaten our security, highlights how UK forces are always on standby, continuously, protecting the UK domestically and influential overseas."
In December, the United States armed forces conducted what it called a "major assault" targeting Islamic State objectives in Syria, after an attack killed two US servicemembers and a civilian interpreter in the Palmyra area.
The U.N. says IS still boasts roughly 5-7 thousand militants in both countries.
