Ukraine intelligence confirms Russia enhanced North Korean missiles to deadly accuracy while Pyongyang supplies troops and weapons, raising nuclear concerns.

Russia and North Korea are perhaps seen as the biggest nuclear threats to peace, but one country stands above them.

SEOUL (Reuters) -North Korean leader Kim Jong Un said in a message to Russian President Vladimir Putin that his country will always stand with Moscow, state media reported on Thursday.

Trump "remains receptive" to reengaging with South Korean strongman Kim Jong Un, White House spokesperson Karoline Leavitt said.

SEOUL (Reuters) -North Korean leader Kim Jong Un inspected military industrial factories, calling them to expand production of shells that meet modern warfare needs, state media KCNA said on Saturday.

North Korea says that leader Kim Jong Un told a top Russian official that his country will “unconditionally support” Russia’s war against Ukraine

North Korea said it has repaired its damaged second naval destroyer and launched the ship into the water in the presence of leader Kim Jong Un, about three weeks after it capsized during a botched launch ceremony.

Russian Railways said it had agreed with North Korea's railways ministry to resume a twice-monthly service between the two capitals on June 17, a journey it said took eight days and which, at over 10,000 km (6,213 miles), was the longest direct rail journey in the world.

North Korean leader Kim Jong-un has said that his country’s ties with Russia have developed into an “indestructible, genuine relationship between comrades-in-arms and alliance.” Kim made the remarks in a congratulatory message he sent to Russian President Vladimir Putin on the eve of Russia Day, according to the Korean Central News Agency (KCNA).

Kim Jong Un, North Korea's leader, reportedly set a deadline for the destroyer's restoration before a party Congress this month.
