Warri- Witnesses say two police officers and a bystander have died in the latest protests over renewed demands for a Biafran state to secede from Nigeria's southeast.
Police Deputy Superintendent Ali Okechukwu said he has reports that at least two officers were killed when protesters opened fire Wednesday in Onitsha city of Anambra state.
A leader of the Indigenous People of Biafra, Ugochukwu Chinweuba, gave a contradictory account, saying police opened fire and a bystander was killed.
Chinweuba said dozens of protesters have been wounded, some critically. He said the protest was disrupted by agitators who set trucks ablaze and attacked police.
Police say more than 130 activists have been arrested recently. One leader is charged with terrorism.
Biafra's separatist cause prompted a 1960s civil war that killed 1 million people.
