Four US marines dead and another injured in Tennessee shooting

Four US marines have been killed and another injured after a shooting in Chattanooga, Tennessee, a military official said.

Shots were fired in a navy reserve centre in the city earlier today.

The wounded marine was hit by gunfire at an armed forces recruiting centre not far away.

The suspected shooter, who has not been identified, is believed to have lived in the area and was shot dead after police swooped on the scene.

‘We are treating this as an act of domestic terrorism,’ said Bill Killian, the U.S. Attoey for the Easte District of Tennessee.

Witnesses said the gunman, driving an open-top Ford Mustang, fired at two locations including a military recruiting center and a US Navy Reserve centre about six miles apart. Witnesses said they heard scores of shots.

A White House spokesman said President Barack Obama had been told about the shooting.

‘The President has been briefed by his national security staff on the Chattanooga shooting, and will continue to get updates as warranted,’ said spokesman Eric Schultz.

Lockdowns were in place at businesses, a college and other facilities near the shooting sites.
