The death toll in a chemical plant explosion in China rose to 64 Saturday but rescuers found a survivor among more than two dozen still missing in the debris of one of the country's worst industrial accidents in recent years. Thursday's explosion in the eastern city of Yancheng injured hundreds and flattened an industrial park. The local fire brigade pulled a man in his 40s from the rubble of the destroyed chemical plant around dawn on Saturday, according to a statement on the city government's official Weibo account.
