A leader of Nigeria’s Jewish community, jailed for a month without charge after being arrested with three visitors from Israel, has been freed. Authorities suspected the visitors had links with a separatist group which had hailed their arrival in Nigeria. Lizben Agha, from the Igbo ethnic group, was released after appeals, including from another African country. Practising Jews form a tiny fraction of the Igbo population, one of the largest groups in multi-ethnic Nigeria. Mrs Agha had been providing assistance to the trio, who came to her community in Ogidi to film part of a documentary.
