Fire officials in Oklahoma believe a fire that destroyed more than 50 homes in suburban Oklahoma City was intentionally set.

The fire started Thursday near a wrecker service where teenagers from a nearby school hang out. A Midwest City fire marshal says no suspects have been identified or a motive determined.

According to the Oklahoma Department of Emergency Management, 49 people have been injured and more than 100 homes have been burned by fires. Fire investigators are still trying to determine what caused the other fires.

The battle against wildfires in western and central Oklahoma and across the state line in Texas eased today as 60 mile-per-hour winds diminished. In Texas, at least three people were killed.

The fires began Thursday afternoon along the Interstate 35, the main north-south highway through central Oklahoma. Parts of the highway reopened Friday after being closed for several hours.
