Thirty people died in China Saturday as a blast ripped through a rural area while a lift crashed on an urban building site. In the first incident, an explosion erupted in the village of Donggancheng, in central China's Henan province, the Xinhua news agency reported. Thirteen people were killed, ten homes collapsed and 60 were damaged in the powerful explosion, Xinhua said. Explosives are widely available in the Chinese countryside, where they are used for construction work, and deadly accidents happen frequently. In the other incident, 17 people died after a construction lift crashed to the ground on a building site. The accident happened in the city of Changsha, capital of Hunan province, also in central China, according to state media and officials.
