The explosions in Tianjin last week have presented the Chinese government with a difficult environmental and political clean-up operation, as it seeks to control both a potentially toxic disaster zone and growing anger among families of the dead and missing.
Yang Jie, 43, was among a few hundred protesters who gathered outside a local government office yesterday. He is demanding information about his son, a 23-year-old firefighter who is missing and presumed dead after a chemical warehouse exploded last Wednesday.
At their most recent press briefing, officials overseeing the rescue effort said the confirmed death toll stood at 112. Another 95 people are missing, most of them firefighters.
