MOSCOW—Hundreds of rescue workers raced bitterly cold weather in Russia’s Ural Mountains region Monday as they searched for survivors in the hulking concrete blocks from a partially collapsed apartment building where at least four people died.
The nation’s top investigative agency, the Investigative Committee, said an explosion triggered by a gas leak apparently caused the pre-dawn collapse in the industrial city of Magnitogorsk. The New Year’s Eve accident shocked Russians and marred the mood on the nation’s most beloved holiday.
