Authorities say two boys rescued two young children from a burning mobile home in central Florida.

Ten-year-old Isiah Francis and 11-year-old Jeremiah Grimes rushed in to a neighbor's home around 11:30 a.m. Tuesday in Orange County after a fire broke out and rescued a 1-year-old and an 8-month-old.

Isiah and Jeremiah say the smoke inside the home was so thick they could barely see.

Fire officials say two other children, ages 2 and 5, who live in the home were injured. One was taken to the hospital via medical helicopter. They were both in critical but stable condition at Arnold Palmer Hospital.

Orange County Fire Rescue says a total of four children and one adult were in the home when the fire broke out.

The cause of the blaze hasn't been determined.
