China evacuates blast zone amid contamination fears

Chinese authorities have evacuated a three-kilometre zone around the Tianjin explosion site over fears of chemical contamination.

New explosions and fires have rocked the Chinese port city of Tianjin as one survivor was pulled out and authorities ordered evacuations to clean up chemical contamination more than two days after a fire and a series of blasts.

Meanwhile, angry relatives of firefighters missing in the disaster stormed a government news conference to demand information on their loved ones.
