A Lone Gunman Reportedly Killed Four Marines in Chattanooga, Tennessee, This Morning

A lone gunman attacked two US military facilities in Chattanooga, Tennessee, late this morning, killing four Marines, the Associated Press has reported. According to a local NBC affiliate, the incident began around 10:45 AM at the US Army Recruiting Center on Lee Highway before concluding at a US Naval Reserve Center about seven miles away.

According to the AP, in addition to the four Marines killed, multiple other people were injured, a Chattanooga police officer among them. The Chattanooga Police Twitter feed informed the public that the shooter had been killed—and the situation effectively neutralized—around 1:15 PM. The officer is said to be in stable condition.

Local, state, and federal law enforcement—including the FBI and Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF)—are reportedly headed to or already at the scene, and the Department of Homeland Security has activated its Chattanooga Strike Team. US Attorney Bill Killian told reporters at a press conference the incident is being treated as "an act of domestic terrorism," CNN reported, though FBI special agent in charge Ed Reinhold told reporters, "We will treat this as a terrorism investigation until we determine it was not."

"We have not determined if it was an act of terrorism or a criminal act," Reinhold added.

Horrific incident in our community. We will release details as they are confirmed. Prayers to all those affected
