Nigerian police fire tear gas as protesters gather over separatist leader

Nigerian police fire tear gas to disperse protesters demanding the release of separatist leader Nnamdi Kanu, head of the banned Indigenous People of Biafra (Ipob). Activist Omoyele Sowore led the protest in Abuja over Kanu's detention on terrorism charges, causing gridlock in the capital. Kanu, a cult hero in south-east Nigeria, faces a long legal battle since his initial arrest in 2015, with his lawyers set to defend him in court.
