Argentine health officials say at least five people have died and five others are critically ill of apparent drug use at a major electronic music festival in Buenos Aires.

Two people in their 20s died during the Time Warp festival on Friday and three others died in an ambulance or at a hospital.

Officials say most of those still hospitalized are in comas.

Dr. Alberto Crescenti heads the emergency medical system for the Argentine capital. He says doctors are trying to determine what sort of drugs caused the deaths.

The city government said Saturday it has closed the center where the concert took place.
