St Louis officers kill 'knifeman'
US police officers in St Louis have shot and killed a 23-year-old man who they say was wielding a knife and refused to drop it.
The incident happened not far from Ferguson, which has seen days of protests over the fatal shooting of 18-year-old Michael Brown by a police officer.
Police Chief Sam Dotson said officers responded to an alert at a store where the man was reported to have stolen energy drinks and a pastry.
Mr Dotson says the man was acting erratically and told responding officers to "shoot me now, kill me now." He says officers opened fire when the man began approaching them with the knife.
KMOV reportsa large crowd gathered at the scene.

St Louis Police Capt Ed Kuntz said police responded after a report of a robbery at the store. The suspect had a knife and refused to drop the weapon.
He said officers opened fire when the man raised the knife and moved toward them.
The suspect was black.
