Chemical warfare troops are working to clear cyanide at the Tianjin blast site before it rains
A deadly chemical explosion in the Chinese city of Tianjin last week still poses a threat to locals with large quantities of cyanide found on the site and the possibility of rain looming, which could release more toxic gases into the air.
Dramatic footage of the explosions circulated online as the disaster unfolded, beginning at a chemicals warehouse and spreading to surrounding facilities.
Authorities, including military chemical warfare specialists, are working on removing more than 100 tonnes of sodium cyanide, which can be fatal within minutes of exposure through inhalation or skin contact, according to the Centers for Disease Control.
