TIANJIN -- Chinese Public Security Minister Guo Shengkun ordered authorities Sunday to release information concerning the Tianjin blasts and rescue operation in a timely and transparent manner, to respond to public concerns.

Speaking at a meeting on rescue work, Guo also urged local authorities to continue to search for survivors while properly disposing of the dangerous chemicals around the blast site and preventing further accidents.

The wounded must be treated with the best medical resources, and psychological assistance should be offered to the injured people and victims' families, he said.
