Death row inmate Troy Davis has been executed in the US state of Georgia for the fatal shooting of policeman Mark MacPhail in 1989.

Davis’ death was delayed for hours while the US Supreme Court considered an 11th-hour appeal for clemency.

The 42-year-old’s case was heavily disputed after most of the witnesses recanted or changed their testimony.

Outside the jail in Jackson, Georgia, there was a heavy police presence earlier as his supporters demonstrated.
