North Korean leader Kim Jong Un has called for his nuclear scientists to increase production of weapons-grade material to make bombs to put on his increasing range of weapons.

The report in state media on Tuesday followed a series of missile launches — seven launch events in this month alone — and rising threats to use the weapons against his enemies.
