North Korea accused the United States on Tuesday of laying the foundation for a potential pre-emptive strike.

North Korean diplomat Ju Yong Chol said at the United Nations Conference on Disarmament that the U.S. is “deploying large nuclear assets” near North Korea in preparation for a possible pre-emptive attack, Reuters reported.
