The Democratic People's Republic of Korea (DPRK) launched short-range missiles into the Sea of Japan on Friday, the Yonhap News Agency reported, citing military sources.

According to the report, the DPRK military test-fired two short- range missiles presumed to be KN-02, estimated to have a range of about 120 km.

The authorities have yet to confirm the exact time of the launching.

The DPRK's launch came after Washington and Seoul began their " Key Resolve" joint military exercises on Monday despite Pyongyang' s warning of annulment of the armistice agreement that halted the 1950-53 Korean War.
