North Korea's Kim Jong Un heads home after Russian journey that raised concern about weapons deals

North Korean leader Kim Jong Un is on his way home from Russia at the end of a six-day trip that raised concerns about weapons transfer deals between two countries locked in standoffs with the West. On his first foreign trip in more than four years, Kim met President Vladimir Putin and visited key military and technology sites in Russia's Far East. He was in a lighter mode Sunday, touring a university and watching a walrus show at a Russian aquarium. Russian state media reported Kim began his return journey following a farewell ceremony at a train station attended by Russia's natural resources minister and the regional governor.
