White fog blankets the ground after 300kg of the chemical spills at a factory in Henan province

An ammonia leak at a chemical factory in Henan province left at least 20 people ill - five with severe symptoms - the mainland media has reported.
A pipeline transporting ammonia at a chemical factory in Shilong district of Pingdingshan city ruptured at around 6.30am yesterday.
About 300kg of ammonia leaked for 15 minutes, creating low-hanging white fog around the area, before the factory brought the situation under control, according to an official statement from the district government.
It said no ammonia was detected in the air about three hours after the rupture.
Photos circulating on social media showed dead dogs, birds and frogs on the ground, and villagers said some children had coughed up blood after inhaling the chemical, according to mainland media.
"Around 5.40am, there was suddenly the sound of an explosion. It was very loud," villager Sun Wenzhen was quoted as saying by The Beijing News.
