Firefighters battled a two-alarm warehouse blaze at 282 Lynnway near Market Street in downtown Lynn Thursday, which also spread to moving trucks parked at an adjacent U-Haul rental location.

Northbound Lynnway near Commercial Street was shut down for the operation, Massachusetts State Police reported, slowing traffic to a crawl. The road has since re-opened for traffic.

WBZ reporter Bernice Corpuz reports that a firefighter was transported to the hospital with minor heat injuries. Witnesses reportedly saw firefighters attending to another victim.

Homeless people were known to live in the building.
