North Korea warns of nuclear 'sacred war'

Pyongyang was ready to launch a "retaliatory sacred war" at any time, the state-run Korean Central News Agency (KCNA) said.

Washington and Seoul say the war games are to deter North Korean aggression.

Tensions between the two Koreas have been high since the sinking of a South Korean warship in March.
