3-Alarm OKC Apartment Fire Kills 4-Year-Old

The Oklahoma City Fire Department confirms a three-alarm fire at the London Square Apartments killed a 4-year-old boy.

One unit was affected the most, sending the boy's mother to the hospital also. The mother is in critical condition.

The father was treated and released at the scene along with two infant children.

The mother grabbed the infants and took them outside before running back in for the 4-year-old.

Other units sustained smoke damage. It is still unclear what caused the fire.

Correction: An earlier version of this story stated four were involved, not five.
