North Korea enters 'state of war' with South
North Korea has said it is entering a "state of war" with South Korea in its latest escalation of rhetoric against its southern neighbour and the US.
A statement promised "stern physical actions" against "any provocative act".
North Korea has threatened attacks almost daily after it was sanctioned for a third nuclear test in February.
