North Korea 'ready to defend itself'

North Korea's supreme leader, Kim Jong-un, has said his country could defend itself in any war started by the US.

He was making a rare public speech as part of mass celebrations involving troops, and military vehicles in Pyongyang to mark the 70th anniversary of the ruling Workers' Party.

Thousands of soldiers - many with red banners - marched past him through the city's main square in tight formation.

An aircraft flypast forming the number 70 flew over the square.

Tanks and missile carriers rolled past the podium where Mr Kim spoke.
