ZHENGZHOU, China, May 19 (UPI) --
Authorities said they suspect a firecracker-workshop explosion that killed three people in China Sunday morning was caused by illegally stored gunpowder.
The blast in Zhengzhou in central China's Henan Province killed the workshop owner's wife and daughter and a neighbor, China's official Xinhua News Agency reported.
The owner and two others have been hospitalized, Xinhua said.
