Authorities in central China say seven workers were killed and two injured after exposure to poisonous gases at a paper mill.

A statement from the Anxiang county government in Hunan province said the accident occurred on Friday after an employee fell into a pool filled with poisonous waste paper pulp during a cleaning operation.

It said his co-workers rushed to help him but were overcome by the noxious gases.
