HATTIESBURG, Miss. – A tornado tore through Hattiesburg on Sunday as part of a wave of severe storms that downed trees, damaged buildings and injured more than a dozen people.

The twister traveled down one of Hattiesburg's main streets and mangled homes, commercial buildings and structures on the campus of the University of Southern Mississippi. Emergency officials said at least 10 people were injured in surrounding Forrest County and three were hurt to the west in Marion County, but they weren't aware of any deaths.

Mississippi Emergency Management Agency spokesman Greg Flynn said it appears that a single tornado caused the damage in those two counties and Lamar County. Hundreds of homes are damaged in Forrest County, along with a couple dozen in the other two. Gov. Phil Bryant declared a state of emergency.
