Death toll from blast rises to 114, with 70 missing

All toxic sodium cyanide within a 3-kilometer radius of the blast site in Tianjin was to be collected and neutralized before Monday evening, He Shushan, the city's deputy mayor in charge of work safety, said at a news conference on Monday.

The chemical, which can be highly toxic in contact with water, was scattered over the 0.1-square-km core area of the blast.
