Rescuers said Sunday they found more bodies at the scene of oil pipeline blasts in eastern China, bringing the death toll in one of the country's worst industrial accidents this year to 52, AP reported. Four more bodies had been found, according to the information office of the government of the port city of Qingdao. Eleven other people are still missing following Friday's explosions from a ruptured oil pipeline owned by China's largest oil refiner, Sinopec. Rescuer efforts were continuing, the information office said. It said earlier that 136 people had been injured, 10 of whom were in critical condition. The pipeline ruptured and leaked for about 15 minutes onto a street and into the sea before it was shut off. Hours later, as workers cleaned up the spill, the oil caught fire and exploded in two locations, the city government said.
