On June 4, 2004 the BBC News reported, "The Nigerian authorities have banned a procession by Muslims in the northern city of Kano, after appeals from Christian leaders. The police outlawed Saturday's march by the Qadiriyya Sufi sect. It has been held annually for 59 years. Dozens of Christians were killed in communal clashes last month in Kano. The Christian Association of Nigeria said it had received information that the march would be hijacked by 'agents of mass killing and destruction.' Religious tensions have been high in Nigeria since the massacre of hundreds of Muslims in the central Plateau State in May. 'The police have no choice but to ban the procession. This is to avoid hoodlums from hijacking it and causing more mayhem,' Kano State police spokesman Mohammed Baba said."
