San Diego and National City firefighters battled a two-alarm fire at a local auto body shop on Sunday.
The fire started around 5:15 p.m. at E&S Autoworks on West 11th Avenue and Hoover Avenue in National City, just east of Interstate 5.
Witnesses tell NBC 7 they heard explosions and then saw flames pouring from the building. The smoke could be seen from the 5 freeway.
A large crowd gathered to watch the activity, which shut down two city blocks. A HAZMAT team also responded.
Fire investigators are trying to determine what caused the fire. Officials did not have an exact dollar amount, but say hundreds of thousands of dollars in damage was done to the business.
