Reports from China say protests broke out in the eastern province of Zhejiang at a factory suspected of pollution.
Witnesses are quoted Monday as saying several villagers were injured when they clashed with police Saturday outside the Tian Neng Battery Company in Meishan. The protesters are said to have burned several police cars and damaged factory and government buildings. There has been no official report of the violence.
Local residents say the battery factory is responsible for high levels of lead that have poisoned their children.
The protest over industrial pollution is the third this year in Zhejiang province.
China has been struck by violent protests in recent months as rural villagers vent anger over industrial pollution and allegations of corruption and unfair land distribution.
