North Korean leader Kim Jong Un called for strengthening the country's nuclear weapons capacity "without limit" and completing war preparations against the United States and its allies, state media reported Monday.

North Korean leader Kim Jong Un vowed to bolster the nation’s nuclear capabilities “without limit” to counter the threats posed by the security partnership between the US and its allies in the region,

The dictator's warning comes after South Korea said last week that North Korean troops had already begun 'engaging in combat operations' alongside Russian forces near the border with Ukraine.

North Korean leader Kim Jong-un has ordered the nation to bolster its nuclear capabilities “without limitation,” emphasizing that this policy is now “irreversible.” He also said Pyongyang would focus all efforts on completing war preparations.
