More than 60 Phoenix firefighters battled a three-alarm strip mall blaze early Sunday.
The fire broke out around 4 a.m., and it burned through ABC Discount Center, KTVK-TV reports. Flames collapsed the discount store's roof, but no one was inside when it fell.
Firefighters worked for more than three hours to knock down the blaze. Although crews were able to contain the fire to the discount store, other units suffered smoke damage.
The cause of the fire is under investigation, according to KTVK.
