N. Korea beefing up weapons

Seoul: North Korea vowed to accelerate its weapons programmes in response to the “evil” sanctions imposed by the UN Security Council following its latest and most powerful nuclear test.

The respected 38 North website in the United States raised its estimate for the yield from the explosion, which Pyongyang says was a hydrogen bomb small enough to fit onto a missile, to around 250 kilotonnes – more than 16 times the size of the device that devastated Hiroshima in 1945.
