A bus filled with people travelling to their home villages in Nepal to receive the first government payments for victims of last year’s devastating earthquake slipped off a narrow mountain road on Monday, killing at least 33 people and injuring 28 others.The bus was heading to Kartike Deurali village, among the worst hit by the quake, which killed nearly 9,000 people in the country. The road, little more than a trail, was wide enough for only one vehicle to pass at a time and was slippery because of continuous rain.A Nepalese home ministry official, Chiranjivi Nepal, said 33 people were killed, but injured passengers and relatives said many more may have died because the wreckage was scattered along the slope below the road and some areas were inaccessible.
