MEMPHIS, TN - Six buildings have caught fire this morning in south Memphis.
At least one of them was a two-alarm fire and at least one of the homes was occupied.
The only known injury has been to a firefighter, who suffered a minor leg injury.
The blazes broke out in three close-by locations over a two-hour period, beginning just before 4 a.m.
Fire officials haven't commented on what started the fires, but authorities have been investigating a string of arsons in the area this spring.
