South Korea's intelligence service said North Korea has revised its constitution to require an automatic nuclear strike if Kim Jong-un is assassinated or incapacitated by a foreign adversary. The move came after the Iran strikes and alongside plans to deploy long-range artillery near the inter-Korean border.

North Korea's revised constitution reportedly requires an automatic nuclear strike if Kim Jong Un is killed, according to intelligence briefings.
