North Korea has sent 10,000 troops to train in Russia and likely fight Ukraine in weeks, Washington said, as Seoul warned Tuesday that the accelerating deployment posed a "significant security threat."

Seoul has long accused the nuclear-armed North of sending weapons to help Moscow fight Kyiv, and after Kim Jong Un signed a mutual defence deal with Russian President Vladimir Putin in June, Pyongyang is alleged to have moved to deploy soldiers en masse.
