British Air Force Typhoon jets have operated alongside French aircraft in a coordinated attack on an underground arms cache in Syrian territory used by the Daesh militant organization, as stated by the British defence ministry.
The facility, pinpointed through surveillance, was assessed as storing arms and explosives, the announcement noted, and was located in mountainous terrain just to the north of the historic site of Palmyra in Syria's central region.
"The RAF jets used Paveway IV guided bombs to strike a number of entry passages down to the site... initial indications are that the objective was successfully hit," officials stated.
There was no evidence of any civilian impact in the strike on Saturday evening and every plane involved made a safe return, the defence officials confirmed.
The Typhoon fighters were backed up by a Voyager aerial refuelling aircraft.
IS - referred to as ISIS - imposed extremist governance over parts of Iraq and Syria prior to its 2019 collapse.
"This operation demonstrates British leadership, and determination to operate in unison with allied nations, to eradicate any revival of IS and their dangerous and violent ideologies in the region," Britain's Defence Chief the Defence Secretary remarked.
UK warplanes have performed surveillance missions over Syria to "prevent any attempted resurgence" of Islamic State following its routing at the climactic battle in Baghuz in 2019, the authorities noted.
"I must thank every member of our armed forces involved in this mission for their expertise and their valour," Healey said. "They were part of a great many UK service members deployed over the holidays. This mission, to remove terrorist threats who pose a risk to our security, shows how UK forces are always on standby, throughout the year, keeping Britain secure domestically and strong abroad."
In December, the American forces conducted what it described as a "large-scale strike" on IS targets in Syria, after an ambush killed two US servicemembers and a civilian linguist in the Palmyra area.
The U.N. says IS still boasts between 5,000 and 7,000 fighters in Iraq and Syria.
