PHILADELPHIA (CBS) – Fire ripped through a row of stores in Southwest Philadelphia early Tuesday morning, seriously damaging several of them and causing detours for some SEPTA lines.

The blaze broke out along the 6000 block of Woodland Road in Southwest Philadelphia around 12:30 a.m. Tuesday.

Fire crews had trouble entering the first floor because of metal grates in front of the storefronts and the narrow alleyway behind the buildings.

Six stores were damaged, four of them heavily. There are no reports of any injuries.

Because crews had to disable trolley lines that hang above Woodland Avenue, there were SEPTA delays in the area. Go to SEPTA.org for more information.
