The fire, which started last week, has been burning for seven days.

Firefighters continue to battle a massive blaze at a Los Angeles warehouse that has been burning for nearly a week, which has spread heavy smoke for miles. As of Tuesday morning, the fire at the Boyle Heights Storage Facility, which stores frozen food, is still ongoing, according to the Los Angeles Fire Department.

Firefighters say they are making progress against the blaze, which began Wednesday at a cold-storage facility. But smoke continued to blow across the region, and the authorities reiterated air-quality warnings.
