North Korea is set to test-fire a new "high range" missile capable of hitting the US mainland, a Russian lawmaker claims.
Anton Morozov revealed Pyongyang's plans as he returned from a five-day visit to the hermit state - where the mood is "rather belligerent" - with a Russian delegation.
He claims North Korean officials gave the Russians mathematical calculations showing that the intercontinental ballistic missile could reach targets on the US west coast.
Morozov told the Russian state-run news agency RIA Novosti: "They are preparing for a new test of a longer-range missile.
"They even gave us mathematical calculations that they believe prove that their missile can hit the western coast of the United States."
He described the mood in Pyongyang as "rather belligerent", adding: "In the near future, they are going to carry out, as far as we understand, yet another launch of a missile, but this time with a longer range."
