Kenyan authorities have suspended three policemen after a newspaper published a picture of an officer apparently shooting a man at point-blank range. Three men are said to have been shot dead in the incident, which took place in central Nairobi. The Kenyan police force has often been accused of carrying out extra-judicial killings. The Daily Nation said that a witness to the killings, which happened on Wednesday on one of the main roads through the city, had taken the pictures. The apparent killing has been condemned by human rights campaign group Amnesty, which said such cases were all too common in Kenya. In 2009 a UN investigation concluded that in Kenya, executions by the police were systematic and widespread.
