Four Marines murdered in US shooting
At least four US Marines were shot dead when a gunman unleashed a barrage of gunfire at two military facilities in the US before he himself was killed.
The fatal shootings at a Tennessee Naval Reserve Center were described by Chattanooga mayor Andy Berke as "incomprehensible".
A US official later said the gunman had been identified as 24-year-old Muhammad Youssef Abdulazeez.
He was believed to have been born in Kuwait, but it was unclear whether he was an American or Kuwaiti citizen. He was from Hixson, Tennessee, just a few miles across the river from Chattanooga.
US Attorney Bill Killian said officials were treating the attacks as an "act of domestic terrorism".
Abdulazeez is believed to have first driven in an open-top Mustang to a military recruiting centre in a strip mall, and peppered the facility with gunfire.
Marilyn Hutcheson, who works just across the street, said: "It was rapid fire, like pow, pow, pow, pow, pow - so quickly. The next thing I knew, there were police cars coming from every direction."
