North Korea has launched 30 short-range rockets into the sea off South Korea's east coast, according to the Associated Press.

Analysts say the impoverished North is angry about the annual drills because it has to spend precious resources responding with its own exercises. Pyongyang claims the allies' drills are invasion preparation.

Major Kim Nam-wook of the South Korean defence ministry said the rockets flew about 37 miles early this morning.
