Royal Air Force Typhoon fighter aircraft have joined forces with French warplanes in a joint strike on an hidden munitions depot in Syria used by the IS group, according to the British defence ministry.
The location, pinpointed through surveillance, was assessed as housing weapons and explosive materials, the release indicated, and was located in mountainous terrain just north of the historic site of Palmyra in Syria's central region.
"Our aircraft employed precision-guided Paveway IV munitions to hit a number of entry passages leading to the site... initial indications suggest the target was engaged successfully," the MoD said.
There was no indication of any civilian casualties in the strike conducted Saturday night and each participating jet made a safe return, the ministry further stated.
The British jets were supported by a Voyager refuelling tanker.
The Islamic State group - also known as ISIS - enforced jihadist rule over significant areas in Iraq and Syria until 2019.
"This operation underscores the UK's leading role, and commitment to work closely with our partners, to eradicate any resurgence of IS and their harmful and extremist ideologies in the area," the British Defence Secretary the minister said.
RAF aircraft have performed surveillance missions over Syria to "prevent any efforts to regroup" of IS after its military defeat at the battle of Baghuz in the year 2019, the authorities noted.
"I extend gratitude to all the members of British forces participating in this operation for their expertise and their courage," Healey commented. "They were among numerous UK service members stationed over the festive period. This operation, to remove dangerous terrorists who endanger our safety, demonstrates how British military are ready to step up, throughout the year, ensuring Britain's security within its borders and powerful internationally."
In December, the American forces carried out what it called a "major assault" targeting Islamic State objectives in the country, after an assault claimed the lives of two US servicemembers and a local interpreter in Palmyra.
The UN estimates IS still maintains between 5,000 and 7,000 fighters in Syria and Iraq.
