North Korea Tests More Missiles as Tensions Grow

North Korea tested five more missiles following a separate guided missile test on Saturday, as the US and South Korea prepare for joint exercises in March.

North Korea fired five short-range missiles into the Sea of Japan on Sunday, South Korea's Yonhap news agency reported, following Saturday's tests of a self-guided missile.

"North Korea kicked off drills of the same kind two weeks earlier than last year," the South Korean Joint Chiefs of Staff spokesman, Jeon Ha-kyu told the agency.

The missile testing began at 4:20 p.m. local time, over the course of 50 minutes, and saw them fly about 200 kilometers before landing in the sea, according to the agency.

Sunday also marks the 67th anniversary of the Korean People's Army (KPA), North Korean news agency KCNA reported.

"Sure is the final victory of the revolutionary cause of Juche and the revolutionary cause of Songun as great Kimilsungism-Kimjongilism indicates the way to be followed by us," North Korean daily Rodong Sinmun wrote in commemoration of the event.

On Saturday, North Korean leader Kim Jong-un observed the test of an anti-ship rocket.

"The ultra-precision anti-ship rocket blasted off from a rocket boat. The intelligent rocket precisely sought, tracked and hit the 'enemy' ship after flying there safely," KCNA reported on Saturday.

The tests come in the run-up to the US-South Korean military drills, which are scheduled to take place this spring on the Korean Peninsula.

Washington and Seoul have repeatedly blamed Pyongyang for developing rocket capabilities that they say are required for the creation of an effective inter-continental ballistic missile.
