RAF Typhoon fighter aircraft have operated alongside France's air force in a combined operation against an hidden munitions depot in Syrian territory used by the Daesh militant organization, according to the British defence ministry.
The facility, pinpointed through intelligence, was believed to be housing weapons and explosive materials, the release indicated, and was located in mountainous terrain just to the north of Palmyra in central Syria.
"The RAF jets used Paveway IV guided bombs to target a number of entry passages leading to the site... preliminary assessments are that the target was engaged successfully," the ministry announced.
There was no evidence of any civilian casualties in the attack conducted Saturday night and each participating jet returned to base without incident, the MoD added.
The British jets were supported by a Voyager aerial refuelling aircraft.
Daesh - also known as ISIS - established jihadist rule over large swathes of both Syria and Iraq prior to its 2019 collapse.
"This strike demonstrates our UK leadership, and resolve to work closely with our allies, to eliminate any revival of the terrorist group and their dangerous and violent ideologies in the region," the British Defence Secretary the Defence Secretary remarked.
UK warplanes have performed overwatch operations over Syria to "deter any attempted comeback" of Islamic State subsequent to its routing at the climactic battle in Baghuz in 2019, the MoD reported.
"I want to thank every member of the UK armed forces who took part in this operation for their skill and their bravery," he said. "They were part of a great many British personnel stationed over the holidays. This action, to take out terrorist threats who endanger our safety, shows how our armed forces are prepared to act, throughout the year, protecting the UK at home and strong abroad."
In December, the United States armed forces executed what it called a "massive strike" against Daesh sites in the country, after an ambush resulted in the deaths of two American soldiers and a local interpreter in Palmyra.
The United Nations estimates Islamic State still has between 5,000 and 7,000 militants in Syria and Iraq.
