After Russian President Vladimir Putin approved a new official doctrine lowering the country's threshold for using nuclear weapons, several media outlets reported that Moscow has started the production of mobile bomb shelters. The emergency ministry's research institute said the 'KUB-M' units would offer protection for 48 hours against hazards – including shockwaves and radiation from a nuclear blast.
