Eight people were killed and around 100 needed hospital treatment after inhaling chlorine gas following an explosion at a water treatment plant in Jos, a city in central Nigeria, Reuters cited the state government as saying on Saturday. A chlorine cylinder exploded at the Lamingo Water Board treatment plant around 4 a.m. (0300 GMT) on Saturday, Plateau state spokesman Samuel Nanle said. "Eight people have been confirmed dead as a result of the inhalation of the contaminated air," he said, adding that 101 people had received hospital treatment for chlorine inhalation. "The contamination has been contained and does not affect the water which has been supplied to public mains," said Nanle.
