North Korean leader Kim Jong Un has returned to Pyongyang, state media said Wednesday, receiving an "ardent" welcome home to the capital after wrapping up a weeklong Russia tour.

Kim's tour of Russia's far east included a summit with President Vladimir Putin, which fanned Western fears that isolated, nuclear-armed Pyongyang could provide Moscow with weapons for its drawn-out invasion of Ukraine.

North Korea's leader inspected everything from Russian space rockets to submarines during the trip.
