Chinese authorities ordered the evacuation of residents within a three kilometre radius of the blast site, as police confirmed the presence of tonnes of the highly toxic chemical sodium cyanide.
Shi Luze, chief of the general staff of the Beijing military region, said cyanide had been identified at two locations in the blast zone.
“The volume was about several hundreds of tonnes according to preliminary estimates,” he said.
