Romania to Mourn Victims of Bucharest Nightclub Blaze

BUCHAREST, Romania (AP) -- A Romanian doctor said Sunday the number of deaths from a horrific nightclub fire and stampede in Bucharest is expected to rise 'significantly' because so many of the injured have severe burns.

Ioan Lascar, a doctor at the Floreasca Emergency Hospital, made the comment as the deaths of two more people brought the overall toll to 29. At least 180 people were injured in the blaze, and over 140 were still hospitalized Sunday.

Arafat said the two had died in the hospital. They were among the 180 injured as they fled a fire and ended up in a panicked stampede Friday night toward the only door in the basement nightclub Colectiv in downtown Bucharest.

Witnesses say the fire erupted after a spark on stage from a heavy metal pyrotechnics show ignited foam decor.

Authorities are still collecting evidence from the scene.

On Saturday, the government declared three days of mourning.
