The DPRK launched the missile off its east coast into the sea of Japan between 11 a.m. and 12 a.m. local time on Monday.

"North Korea (DPRK) fired one KN-02 short-range missile today. South Korean military will closely monitor the North Korean (DPRK) military in case of any further launch," Yonhap News Agency said quoting Seoul military official.
