A man suspected of shooting a Virginia news crew dead during a live broadcast has uploaded camera phone footage of the attack to his Twitter account.
The film shows the full attack, including the shooting, and is severely graphic in nature.
Vester Lee Flanagan aka Bryce Williams tweeted about his role in the shooting.
He uploaded the footage to the social network just after 4.15pm BST.
Initial reports that the gunman had killed himself, confirmed by the Augusta sheriff's office, now appear to have been premature.
The condition of the gunman is unknown, with reports saying that he is still alive.

The account was almost immediately suspended.
The gunman also sent a fax message to a local ABC news affiliate last night, reports said.
