Russian emergency crews have rescued more than 250 people, including 28 children, after a powerful snowstorm left dozens of cars and buses trapped in deep snowdrifts on a highway in Zabaikalsky Krai (a sparsely populated region in Russia's Far East, bordering Mongolia and China). Rescue teams spent the day digging out vehicles and transporting stranded travellers to temporary shelters. Authorities warned of further snowfall expected on Tuesday and urged drivers to postpone travel, with conditions forecast to improve later in the week as temperatures rise.
