Rights Group, Nigeria Officials Differ on Lekki Shooting Death Toll Timothy Obiezu ABUJA - Human rights group Amnesty International and authorities in Nigeria disagree on the number of people killed at a shooting Tuesday in Lagos. Amnesty International says at least 56 protesters have died in clashes with security forces during weeks-long demonstrations in Nigeria against police brutality, with at least 38 people killed Tuesday -- 12 of them when security forces opened fire on unarmed protesters at the Lekki toll gate in Lagos. While authorities have acknowledged some casualties, they are downplaying the numbers, and the army has denied firing on protesters. Amnesty International released its latest figure in a statement Wednesday night, citing evidence from witnesses. .
