Japan closes beach over "mysterious ball"

(RT) ⸻ Police are investigating a large spherical object found on a beach in a Japanese city, which may be some kind of sea mine. It measures around 1.5 meters (4.9 feet) in diameter and may be made of iron. Police have cordoned off the area and called the Japanese Self-Defense Forces to inspect it for explosives. The hunt for mysterious round objects has intensified after the US accused China of flying a "spy balloon" through its airspace.
