A statement issued on Friday in Minna by Alhaji Ahmed Inga, the Director General of Niger State Emergency Management Agency (NSEMA), said a seven-day-old child and seven-year-old girl were the victims.
Inga said the incident occurred at about 9:30pm.
He added that the mother of the two minors was also injured in the incident.
Inga also disclosed that the mother of the deceased was responding to treatment, adding that government would take full responsibility of her upkeep.
“ The owner of the collapsed wall was given a warning by the neighbours over the poor structure of the wall, but he refused to yield to the advice.
“It was not windstorm that led to the collapse of the wall, but the poor way in which it was built,’’ Inga stated.
He appealed to residents to respect government laws, saying appropriate punishment awaited any act of negligence displayed by owners of buildings or contractors.
