Royal Air Force Typhoon jets have conducted a mission with France's air force in a combined operation against an hidden munitions depot in Syrian territory employed by the IS group, per a report from the UK's MoD.
The location, identified by surveillance, was assessed as housing weapons and explosive materials, the statement said, and was located in mountainous terrain just north of the ancient city of Palmyra in central Syria.
"Our fighter planes used Paveway IV guided bombs to target a number of approach shafts providing entry to the facility... initial indications are that the target was engaged successfully," officials stated.
There was no indication of any civilian impact in the strike late on Saturday and each participating jet made a safe return, the defence officials confirmed.
The British jets were supported by a Voyager aerial refuelling aircraft.
IS - referred to as ISIS - enforced jihadist rule over large swathes of Syria and Iraq prior to its 2019 collapse.
"This action underscores our UK leadership, and determination to operate in unison with our partners, to stamp out any revival of Daesh and their harmful and extremist ideologies in the area," UK Defence Secretary John Healey said.
British military aircraft have performed overwatch operations over Syria to "deter any efforts to regroup" of the group after its routing at the climactic battle in Baghuz in 2019, the authorities noted.
"I extend gratitude to every member of the UK armed forces involved in this operation for their expertise and their bravery," the Defence Secretary commented. "They were among numerous British personnel on duty over Christmas and New Year. This operation, to take out dangerous terrorists who endanger our safety, highlights how our armed forces are ready to step up, all year round, ensuring Britain's security domestically and influential overseas."
During December, the US military executed what it described as a "massive strike" on IS targets in Syria, subsequent to an assault claimed the lives of two US servicemembers and a local interpreter in Palmyra.
The UN estimates Islamic State still boasts an estimated 5,000 to 7,000 militants in Iraq and Syria.
