An American death-row inmate whose conviction has stirred widespread controversy has been executed in the state of Georgia for the fatal shooting of a policeman in 1989.
The execution was delayed for more than four hours while the United States Supreme Court considered - and eventually rejected - an 11th-hour appeal for clemency for Troy Davis.
The 42-year-old's conviction and sentencing for killing Mark MacPhail has been heavily disputed since most of the witnesses in the case recanted or changed their testimony, the BBC reports.
Outside the jail in Jackson, there was a heavy police presence earlier as his supporters demonstrated.
Davis addressed the family of Mr MacPhail before the sentence was carried out by lethal injection on Wednesday night and told them he was not responsible for Mr MacPhail's death.
