5 dead, including 4 Marines and gunman, in Tennessee shootings

A gunman opened fire Thursday at two military facilities in Chattanooga, Tennessee, WRCB reports.

Andy Berke, the mayor of Chattanooga, confirmed that five people are dead, including four Marines and the gunman.

"We are treating this as an act of domestic terrorism," said Bill Killian, the U.S. Attorney for the Eastern District of Tennessee, adding that no official determination of the nature of the crime had yet been made.

Three others were wounded in the attacks that began at about 10:45 a.m. local time and ended about 30 minutes later.

Witnesses and local media reports said the gunman, driving an open-top Ford Mustang, fired at two locations including a military recruiting center and a US Navy Reserve center about six miles apart.
