BOSTON (AP) — Boston fire officials say a blaze broke out at a warehouse in Hyde Park sending up thick black smoke that could be seen miles away.

The fire department says on its Twitter page that the fire broke out about 5:40 p.m. Saturday at Hyde Park Masonry and Landscape Supplies. Because of the smoke, some apartment houses nearby were evacuated. No serious injuries were reported.

Fire officials say they aren't sure what materials are burning but believe tanks of hazardous gases are inside the building. They expected to be working the fire through the night.

The single-story cinder block building has few windows. Flames shot through the top of it as the fire burned, and part of the roof collapsed.
