Rescue workers on Friday morning gained access to the upper floors of the 355-room Grand Diamond City Hotel and Casino in Poipet, in Cambodia, after most of the casino was razed by a 12-hour blaze that erupted in its main gambling room late on Wednesday night, witnesses told The Nation.

At least 19 people were killed and up to 30 were missing after a huge fire tore through a casino-hotel complex in a Cambodian town on the Thai border, officials said on Thursday.
