Facebook says it removed the page of Nigerian separatist leader Nnamdi Kanu for violating its rules on harm and hate speech.
Mr Kanu’s page was eliminated for repeated violation of its community rules, the social networking site told the BBC.
He had made a video post of a militia group attacking and killing cattle in a herders’ settlement.
He also used the live broadcast to accuse herders of distracting farmlands in eastern Nigeria.
The conflict between herders and other groups is currently one of Nigeria’s hottest political issues.
Mr Kanu leads the Indigenous People of Biafra (Ipob), which campaigns for independence for Nigeria’s south-eastern region, where the ethnic Igbo people form the majority.
The herders are usually from the northern Fulani community in the country.
Mr Kanu, who also has British nationality, used his Facebook page as a key platform to communicate with his followers around the world. The account is said to have been blocked on Tuesday.
