Rescuers on Friday were searching through rubble that buried a passenger bus in the central Chinese province of Hubei with little hope for the survival of 30 people believed to have been on board the vehicle, state media said, according to dpa. The bus company in Enshi prefecture reported the bus missing Wednesday, but its location was only discovered when emergency workers were searching the site of a landslide further up the hill where one worker died and two were missing at a railway tunnel construction site. The rescuers had dug out the front of the bus by Friday morning but found no signs of life, the official Xinhua news agency quoted officials as saying. A total of 27 passengers, two drivers and one conductor were on the bus Tuesday as it was returning to the mountainous area from Shanghai, the bus company said. The landslide left about 1,000 cubic metres of rubble on National Highway 318, a major route through western Hubei, the agency said.
