China power station explosion kills at least 21

A pipeline explosion at a power station in China killed at least 21 people and injured five more on Thursday, the official Xinhua news service reported. The blast, which Xinhua said happened in a high-pressure steam pipeline, came a day before the first anniversary of giant explosions that killed at least 165 people in the northern port city of Tianjin. The latest incident occurred at a coal-fired power plant in Dangyang, in the central province of Hubei, and rescue efforts were underway, reports said.
A photograph purportedly from the scene showed a bare concrete shell and metal scaffolding standing by a smokestack. The local government said it was investigating the cause.
