Western aircraft have been conducting patrols to stop a resurgence of the terror group, the ministry noted.

"The area around the facility is devoid of any civilian habitation," the statement clarified.

"Our aircraft used Paveway IV guided bombs to target a number of access tunnels down to the facility," the ministry added, noting that initial indications are that the target was successfully engaged, and that no civilians were put at risk by the strikes.

"This action shows our UK leadership and determination to stand shoulder to shoulder with our allies, to stamp out any resurgence of ISIS and their dangerous and violent ideologies in the Middle East," British Defense Secretary John Healey commented following the announcement.

"I want to thank all the members of our Armed Forces involved in this operation – for their professionalism and their courage," he added.

"This operation, to eliminate dangerous terrorists who threaten our way of life, shows how our Armed Forces are ready to step up, all year round, keeping Britain secure at home and strong abroad," he concluded.

ISIS's December attack on US forces in Palmyra

ISIS was responsible for an attack on US personnel in the same area on December 13.
"Two US service members and one US civilian were killed, and three service members were injured as a result of an ambush by a lone ISIS gunman in Syria. The gunman was engaged and killed," CENTCOM said.

As a result, Syria's Interior Ministry, the following day, arrested five suspects with links to the attack.
