N. Korea fires 'unidentified ballistic missile': South Korea's military

Seoul: North Korea has fired an "unidentified ballistic missile", Seoul's military said Thursday, the latest in a record-breaking blitz of launches that came just hours after Pyongyang warned of a "fiercer" military response to the US and its regional allies.

"North Korea fires an unidentified ballistic missile into East Sea," South Korea's Joint Chiefs of Staff said, referring to the body of water also known as the Sea of Japan.
