Five soldiers have been injured in a shooting by a sergeant at one of America's largest army bases. Officials have named the attacker as Sergeant Quornelius Radford, 28, who used a personal handgun rather than a military weapon during the incident. It happened at Fort Stewart in Georgia, and forced a brief lockdown at the facility from just after 11am local time on Wednesday. Radford was arrested after being tackled by other troops, who "without a doubt, prevented further casualties or wounded",
