The Democratic People's Republic of Korea (DPRK) would not tolerate provocation by the United States and South Korea, Kim Yong Nam, president of the Presidium of the DPRK Supreme People's Assembly, said Tuesday.

According to the official KCNA news agency, Kim said the DPRK army and people would "never tolerate" reckless moves by the United States and South Korea to provoke a nuclear war, and would launch a "sacred retaliatory war" of their own style "based on nuclear deterrent" any time.

Kim warned the DPRK army and people would take "the toughest self-defensive measure" and "mercilessly beat back the aggressors and surely accomplish the historic cause of national reunification."

The DPRK would steadily work hard to ensure the support to and solidarity with the countries that support the DPRK's revolutionary cause on the principles of independence, peace and friendship, Kim said.
