The United Kingdom’s Ministry of Defence announced that the Royal Air Force, in coordination with France, carried out a joint airstrike on Saturday night targeting an underground facility in Syria. The site was believed to be used by ISIS for storing weapons and explosives. Officials stated that the target was located in a sparsely populated area and that the operation posed no risk to civilians.

Although ISIS was territorially defeated in Syria in 2019, the group remains active in the country’s desert regions. Palmyra, known for its UNESCO-listed ancient ruins, was previously under ISIS control. The latest strike follows an attack last month in Palmyra by a lone ISIS gunman that killed two U.S. soldiers and one American civilian. In response, U.S. forces launched airstrikes on several ISIS targets across Syria.

The joint UK-France operation underscores continued international efforts to suppress ISIS activities in Syria’s remote areas following renewed militant attacks.
