Brazil night club fire

Panic intensified when security guards locked the exit. Media reports said the guards were unaware of the blaze and tried to stop people from leaving the building without paying.

A similar incident occurred in Russia in late 2009 when a deadly fire swept through the Lame Horse night club in Perm, 1,400 kilometers east of Moscow after an indoor firework display set the ceiling ablaze, quickly filling the packed club with toxic smoke and killing a total of 156 people.
