(Adds quotes, details) NAIROBI, Feb 25 (Reuters) - The U.N. investigator into extrajudicial killings in Kenya called on Wednesday for the dismissal of police chief Hussein Ali and the resignation of attorney-general Amos Wako over killings by security forces. U.N. rapporteur on extrajudicial, summary and arbitrary executions Philip Alston made the recommendations at the end of a damning report into the killings of hundreds of suspected Mungiki gang members, rural rebels and political demonstrators. "I have received overwhelming testimony that there exists in Kenya a systematic, widespread and well-planned strategy to execute individuals, carried out by the police," he said of the alleged killing of some 500 suspected Mungiki members. "Kenyan police are a law unto themselves. They kill often, with impunity," he said. Alston said his 10-day visit had backed the reports of witnesses and rights groups of the Mungiki killings, the illegal shooting of scores during last year's post-election violence, and the killing of some 200 suspected rebels under interrogation and torture in the western Mount Elgon area. He lambasted police boss Ali for failing to give him any information in response to allegations against his force. And of the attorney-general, he said: "Mr Wako is the embodiment in Kenya of the phenomenon of impunity." (Reporting by Andrew Cawthorne)
