RAF Typhoon FGR4s have operated alongside French aircraft in a combined operation against an underground arms cache in Syrian territory used by the Islamic State group (IS), as stated by the British defence ministry.
The site, pinpointed through intelligence, was thought to be housing weapons and explosive materials, the release indicated, and was located in mountainous terrain just north of the ancient city of Palmyra in central Syria.
"Our aircraft utilized Paveway IV guided bombs to target a series of entry passages down to the facility... initial indications are that the strike was effective," the ministry announced.
There was no indication of any civilian casualties in the strike late on Saturday and each participating jet made a safe return, the defence officials confirmed.
The Typhoon fighters were backed up by a Voyager tanker plane.
Daesh - alternatively referred to as Daesh - imposed extremist governance over parts of Syria and Iraq before its territorial defeat in 2019.
"This operation underscores British leadership, and resolve to operate in unison with allied nations, to eradicate any revival of IS and their violent and radical beliefs in the area," the British Defence Secretary the Defence Secretary remarked.
British military aircraft have conducted overwatch operations over Syria to "deter any attempted comeback" of Islamic State after its military defeat at the climactic battle in Baghuz in the year 2019, the ministry said.
"I extend gratitude to every member of British forces who took part in this operation for their skill and their courage," the Defence Secretary commented. "They were among numerous British troops stationed over Christmas and New Year. This mission, to take out dangerous terrorists who endanger our security, highlights how UK forces are prepared to act, all year round, protecting the UK domestically and strong abroad."
During December, the United States armed forces carried out what it termed a "massive strike" targeting Daesh sites in the country, after an ambush killed two US troops and a civilian interpreter in the Palmyra area.
The UN estimates IS still boasts between 5,000 and 7,000 militants in both countries.
