Opponent and Cameroonian presidential candidate Maurice Kamto has been prevented from entering the headquarters of his party, the Movement for the Renaissance of Cameroon (MRC), in Douala by the forces of law and order, even though a large number of supporters were waiting for him there for a meeting. "The police prevented us from going to the headquarters. We're overwhelmed," said one supporter, Martin Kam. It is ‘impossible’ to get to the MRC headquarters, Kamto also said on the MRC Facebook page. IMAGES AND SOUNDBITES
