Chinese authorities have ordered the evacuation of residents within a 3km radius of the Tianjin blast site over fears of chemical contamination. The evacuations came after an apparent change in wind direction, and as police confirmed the highly toxic chemical sodium cyanide was found near the site.
At least 112 people died in the blasts, officials said on Sunday, and more than 700 have been hospitalized. Officials have identified 24 of the dead, with 88 still to be identified. Remarkably, a man was found alive just 50m from the blast core, Chinese state news agency, Xinhua reported. The man was able to talk when he was found and is now in hospital, according to the report (BBC News, 2015).
