Nigerian senators representing the South-East region of Nigeria, the west African country, have urged the government to investigate allegations that security forces killed around 150 people calling for the independence of Biafran territories.
Rights group, Amnesty International, accused security forces of firing live bullets on unarmed protesters earlier in May.
Most of the demonstrators were members of the separatist group, Indigenous People of the Biafra (Ipob). Pro-Biafrans are demanding the independence of territories forcibly annexed to modern-day Nigeria during British colonisation, which ended in 1960.
