Biafra shutdown cripples Nigerian cities A stay-at-home protest by Biafran separatists in Nigeria has crippled cities and towns in the south-east. Streets are empty and markets, banks and schools are closed to mark the abortive attempt in 1967 to gain independence for the region. It led to a bitter three-year civil war in which more than one million people were killed. The authorities have warned the secessionists against street protests and security forces are on patrol. South-eastern Nigeria is mainly inhabited by the ethnic Igbo community, who often complain of marginalisation - accusing successive governments of failing to develop their areas.
