OKLAHOMA CITY (AP) — Firefighters discovered the bodies of a woman and four children on Wednesday after a predawn blaze ripped through a house on the city's northwest side, fire officials said.

The children, who range in age from 2 to 8 years old, and the woman were found inside the house after firefighters arrived at the two-story, wood-frame home shortly after 6:30 a.m., Fire Department Maj. Tammy McKinney said. A man also is in critical condition at a local hospital, she said.

"When we got on scene, we had reports that there were children inside," McKinney said. "The fire was so intense that we could not make entry and had to knock the fire down before we could make entry. That's when we found the bodies."
