The Cambodia casino was smoldering at sunset this evening with flames still burning after a fire that killed at least 19 people, seen here on Thursday (December 29).

Dozens of revelers still remain missing following the inferno at the Grand Diamond City Hotel and Casino in Poipet which erupted shortly before midnight on Tuesday evening.

The fire rapidly grew and spread to the building's upper storeys reportedly due to windy conditions last night, rescuers said.

Dozens of fire crews including teams from neighboring Thailand, a short drive across the border, raced to the inferno.

It reportedly took more than six hours to bring it under control but at 6 pm local time, the remnants of the fire were continuing inside the building.

Officials had cordoned off the area around the blackened ruins - still with smoke coming from them - and declared a no-entry zone amid evacuations.

A provisional police report said that 'around 10 people' - many of them reportedly Thai nationals - have been killed but the figure rose.

An estimated 400 people were inside the building when the fire broke out, with around 50 believed to have been trapped inside. Some 30 others were also reported injured.

The revelers were stranded on top of the building and jumped to their deaths.

Graphic footage was also taken showing people plunging from windows and the roof of the building to escape the flames.

The cause of the fire is still unclear.

Casinos are legal in Cambodia and popular with tourists from Thailand and China, where both countries ban gambling.
