According to the backinfo I got, this happened in Venezuela. The video shows lynching of an alleged thief by a mob.
The thief is already beaten to a near pulp when the video starts. The mob drags him a bit to a place where they douse him with gasoline and set him on fire. There, as the dying man screams, the mob has a chuckle.
Props to Best Gore member @seraphim-serenata for the video:
