BEIJING Aug 3 (Reuters) - An explosion that ripped through a motor wheels factory in the eastern China province of Jiangsu killed 71 people and injured 186, the official Xinhua news agency said on Sunday.
Earlier it had said the blast, that occurred on Saturday, killed 69 and injured roughly 200.
The accident at the Zhongrong Metal Products Co Ltd plant, which makes aluminium wheels for automakers including General Motors Co <GM.N), was China's worst industrial accident in a year.
According to Zhongrong's website, the factory made wheels that are supplied to GM and many other carmakers.
The blast at the Zhongrong workshop occurred around 7:30 a.m. on Saturday in Kunshan city, about an hour's drive from Shanghai.
A preliminary investigation suggested the blast was triggered when a flame was lit in a dust-filled room, the local government said at a news conference on Saturday, describing the incident as a serious safety breach.
