Kenyan police denied allegations that officers shot dead seven suspected armed robbers in cold blood in one of Nairobi's bloodiest incidents in months.Witnesses quoted in newspaper reports said the suspects were executed as they lay face down on the ground after being ordered off a bus, but police said their men acted in self-defence.Human rights groups accuse the police of often shooting suspects instead of arresting them, charges the police deny.
