North Korean leader Kim Jong-un has said the US is his country's "biggest enemy" and pledged to expand North Korea's nuclear weapons arsenal and military potential. He stated this, addressing a rare congress of his ruling Workers' Party, BBC reports.
He said that plans for a nuclear submarine were almost complete.
In his latest address to the Workers' Party - only the eighth congress in its history - Mr Kim said Pyongyang did not intend to use its nuclear weapons unless "hostile forces" were planning to use them against North Korea first.
He said the US was his country's "biggest obstacle for our revolution and our biggest enemy... no matter who is in power, the true nature of its policy against North Korea will never change."
His speech outlined a list of desired weapons including long-range ballistic missiles capable of being launched from land or sea and "super-large warheads".
North Korea has managed to significantly advance its arsenal despite being subject to strict economic sanctions.
As we reported earlier, president of the Russian Federation Vladimir Putin has signed a decree awarding North Korean leader Kim Jong-un with the "75 Years of Victory in the Great Patriotic War of 1941-1945" jubilee medal.
