RESERVE, N.M. (AP) — New Mexico's largest wildfire in recorded state history has grown to nearly 339 square miles.

Fire officials said Friday that the massive blaze in the Gila National Forest scorched an additional 39 square miles in the past day. The fire has burned nearly 217,000 acres in an isolated mountainous area of southwestern New Mexico.

The incident management team says more than 1,200 firefighters are battling the fire that so far has injured six people. Officials say the fire is around 10 percent contained.

Forecasters say there's chance for thunderstorms and dry lightning over the Black Hills area that could spark fires.

The fire is the largest currently burning in the country.
