Rescue work has resumed this morning a day after at least 46 people were killed and several injured following a massive landslide that buried two government-run buses in Himachal Pradesh's Mandi district, officials said. The number of people killed could rise as over 50 passengers were travelling in the two buses hit by the landslide at Kotpuri near Padhar on the Mandi-Pathankot national highway which was triggered by a cloudburst, they said.
