SANTO DOMINGO, Dominican Republic (AP) -- Authorities in the Dominican Republic say they are investigating 11 deaths at the main children's hospital in Santo Domingo.
Among those who died over the weekend were eight children who were less than a year old, including three newborns.
The director of the Robert Reid Cabral Children's Hospital says the deaths coincided with a breakdown of the hospital's ventilation system but denies that was to blame.
Rosa Nieves told radio station Z101 on Tuesday that the children who died were in the intensive care unit in serious condition and suffered from various ailments. She said that they received mechanical and manual ventilation after the system failed.
