OIL CITY — Wildfires in northwestern Louisiana have burned at least 500 acres and three homes near the town of Ida and forced the evacuation of scores of residents, The Associated Press has reported.

Caddo Parish Sheriff Steve Prator said the fires started over the weekend in northern Caddo Parish. Firefighting crews were dispatched from parish fire districts, nearby towns and cities and eastern Texas and southern Arkansas.

No injuries were reported.

Prator said the fire near Ida started across the state line in Arkansas and jumped the Interstate 49 construction corridor. Two structures, along with an undetermined number of fishing huts in the woods near Caddo Lake, also burned.

A state forestry helicopter with a large bucket took water from Caddo Lake on Monday and dumped it on one of the fires.
