British Air Force Typhoon fighter aircraft have joined forces with French aircraft in a joint strike against an subterranean weapons facility in Syrian territory operated by the Islamic State group (IS), as stated by the UK's MoD.
The site, pinpointed through surveillance, was thought to be containing munitions and bombs, the release indicated, and was positioned in mountains just above the historic site of Palmyra in Syria's central region.
"Our aircraft used Paveway IV guided bombs to target a several access tunnels providing entry to the site... preliminary assessments suggest the objective was successfully hit," the MoD said.
There was no evidence of any civilian impact in the attack on Saturday evening and each participating jet made a safe return, the defence officials confirmed.
The Typhoon fighters were supported by a Voyager aerial refuelling aircraft.
The Islamic State group - alternatively referred to as ISIS - established militant control over large swathes of Iraq and Syria until 2019.
"This action shows the UK's leading role, and commitment to work closely with our allies, to eradicate any resurgence of IS and their dangerous and violent ideologies in the region," Britain's Defence Chief the minister remarked.
UK warplanes have performed surveillance missions over Syria to "deter any attempted resurgence" of Islamic State following its defeat at the climactic battle in Baghuz in 2019, the ministry said.
"I must thank the personnel of our armed forces who took part in this strike for their expertise and their courage," Healey added. "They were part of a great many British troops stationed over Christmas and New Year. This mission, to eliminate terrorist threats who pose a risk to our security, shows how our armed forces are always on standby, all year round, ensuring Britain's security domestically and influential overseas."
Last December, the United States armed forces executed what it called a "massive strike" against Daesh sites in Syria, following an assault resulted in the deaths of two US servicemembers and a local interpreter in the Palmyra area.
The UN estimates Daesh still has an estimated 5,000 to 7,000 militants in both countries.
