North Korea is prepared to respond to any nuclear attack by the United States in kind, the country's number two official said Saturday.

"We're prepared to respond to an all-out war with an all-out war and we are ready to hit back with nuclear attacks of our own style against any nuclear attacks," Choe Ryong-Hae said in a speech at a ceremony before a large military parade started, which was broadcast live by the North's Korean Central TV.
