NEW YORK, May 24 (Xinhua) -- The Democratic People's Republic of Korea (DPRK) fired an unspecified ballistic missile eastward on Wednesday Pyongyang Time, South Korea's Yonhap news agency reported, quoting military sources.

       The news was announced by the Joint Chiefs of Staff of South Korea. Details were not immediately available.

       Earlier this month, the DPRK launched what was thought to be an ICBM and then an apparent submarine-launched ballistic missile - in a move seen as an effort to diversify nuclear delivery vehicles, according to the report.
