Russia warns Ukrainian forces to surrender 'immediately' as nuclear war threat grows

With more than 50 days into the war in Europe, Russia on Tuesday warned Ukrainian forces to immediately lay down all arms.

The warning has come amid reports that Russia is planning to launch a nuclear offensive against Ukraine.

Russia's threat has come amid Zelenskyy's Saturday warning to the word that it should be prepared for a "number of ways" for the possibility of Russia might using nuclear weapons. However, the Ukrainian President did not give any evidence for such an assertion.

"The world doesn't need to wait. The world needs to prepare," Zelenskyy told reporters at a briefing.

Earlier, Kremlin Press secretary Dmitry Peskov had said that Russia will only resort to nuclear weapons if it feels there is a threat to its own existence.
