5 children hospitalized following house fire in Detroit

Five children have been injured in a house fire in northwest Detroit.

Investigators say a mattress caught fire in one of the bedrooms.

The mattress was found near a space heater with melted plastic-hangers and several lighters.

Deputy fire commissioner Dave Fornell says the children, three girls and two boys, -- ages 4 months to 4 years old -- were taken to a hospital Thursday morning. The children suffered from smoke inhalation. Their conditions were not immediately available.

A firefighter also suffered an injury while trying to enter the home. His injury was not considered life-threatening.

The fire was reported about 9:20 a.m. and is under investigation. Police said adults inside the home put the blaze out before firefighters arrived.
