Neuclear Test

New radar satellite images show the Sept. 3 nuclear test by North Korea was powerful enough to sink a roughly 85-acre area on the peak of a mountain above the tunnels where the test likely took place.

The top North Korean official for US relations told The Associated Press on Friday that his country is now a nuclear threat to be reckoned with, and Washington can expect more nuclear tests and missile launches like the ones earlier this week as long as it attempts to force his government's collapse through a policy of pressure and punishment.

North Korea's claim Wednesday that it had tested a hydrogen bomb alarmed Pyongyang's Asian neighbors -- and the rest of the world. We take a look at what's behind this new North Korean claim.

The head of an international body set up to monitor a planned ban on nuclear testing condemned North Korea's fourth nuclear test today and called it a "wake-up call" for the international community.

Japanese Prime Minister Shinzo Abe said today the nation would make a firm response to North Korea's challenge against nuclear non-proliferation, calling its latest nuclear test a threat to Japan's security.
