Three more Nigerians including the parents of the deceased children, two Uzbeks and a Russian sustained injuries, and 37 people were evacuated.
The bereaved parents sustained burns and are receiving medical treatment at a hospital. Their youngest child -- a 2-year-old girl -- evacuated with the parents.
