A motel under construction collapsed as a massive fire ripped through the unfinished building early Tuesday morning in northwest Harris County.

The blaze broke out about 3 a.m. at the four-story structure at 13200 block of the West FM 1960 near Hempstead Highway, according to the Harris County Fire Marshal's Office

One firefighter who had minor burns was taken to the hospital. He was in stable condition.

The flames forced officials to evacuate an occupied motel next door to the burning building. Firefighters protected that motel from damage.

The massive blaze sent heavy smoke into the predawn sky. Embers sparked grass fires in nearby empty fields that were doused quickly.

Firefighters were still at the scene hours later pouring water on the charred, smoldering rubble.

Investigators were trying to determine how the fire was ignited.

Portions of FM 1960 near the fire were temporarily shutdown while crews battled the blaze.
