The Democratic People's Republic of Korea (DPRK) fired a ballistic missile on Wednesday, news agency Yonhap of the Republic of Korea (ROK) reported, citing the ROK's Joint Chiefs of Staff.

The missile flew to the east and the ROK's military is analyzing details of the launch with the US, ROK's joint chiefs said, according to the report.

Two authoritative US government sources said earlier that US government experts believed the DPRK could conduct a new missile test within days  in what would be its first launch since it fired a missile over Japan in mid-September.
