Jomo Kenyatta guerrillas, Kenyatta sent soldiers into the region in December 1963 and gave them advanced powers of arrest and seizure in the NFD in September 1964. British troops were assigned to assist the Kenyan Army in the region. Kenyatta also faced domestic opposition and in January 1964, sections of the army launched a mutiny in Nairobi, with Kenyatta calling on the British Army to put down the rebellion. Similar armed uprisings had taken place that month in neighbouring Uganda and Tanganyika. Kenyatta was outraged and shaken by the mutiny. He publicly rebuked the mutineers, emphasising the need for law and order
Jomo Kenyatta insisted that it was necessary; in a March 1961 speech, he described Kenyatta an "African leader to darkness and death" and stated that if he were released, violence would erupt. This indefinite detention was widely interpreted internationally as a reflection of the cruelties of British imperialism. Calls for his release came from the Chinese government, India's Nehru, and Tanganyika's Prime Minister Julius Nyerere. Ghana's President Nkrumah personally raised the issue with British Prime Minister Harold Macmillan and other UK officials, with the Ghanaian government offering Kenyatta asylum in the event of his release. Resolutions calling for his release were produced
