British Air Force Typhoon jets have conducted a mission with French warplanes in a combined operation targeting an hidden munitions depot in Syria operated by the IS group, per a report from the UK Ministry of Defence.
The location, located using intelligence, was assessed as housing weapons and explosive materials, the release indicated, and was positioned in hills just above the ancient city of Palmyra in central Syria.
"Our aircraft employed Paveway IV guided bombs to strike a number of entry passages down to the facility... initial indications suggest the strike was effective," the ministry announced.
There was no indication of any civilian casualties in the attack on Saturday evening and each participating jet returned to base without incident, the defence officials confirmed.
The Typhoon FGR4s were assisted by a Voyager aerial refuelling aircraft.
IS - also known as ISIS - imposed militant control over large swathes of both Syria and Iraq until 2019.
"This action shows British leadership, and commitment to work closely with our partners, to stamp out any revival of Daesh and their violent and radical beliefs in the Middle East," the British Defence Secretary the Defence Secretary stated.
RAF aircraft have performed patrols over Syria to "prevent any attempted resurgence" of Islamic State following its routing at the climactic battle in Baghuz in 2019, the ministry said.
"I want to thank the personnel of British forces participating in this mission for their expertise and their courage," Healey added. "They were part of numerous UK service members stationed over Christmas and New Year. This action, to remove terrorist threats who pose a risk to our way of life, demonstrates how UK forces are ready to step up, continuously, ensuring Britain's security at home and influential overseas."
During December, the US military carried out what it termed a "major assault" against Daesh sites in the country, following an assault resulted in the deaths of two American soldiers and a civilian linguist in the Palmyra area.
The U.N. reports Islamic State still boasts between 5,000 and 7,000 militants in Syria and Iraq.
