The wife of the leader of the Indigenous People of Biafra (IPOB),  Uchechi Okwu-Kanu, wrote to Newsweek earlier in October to say she was sure that her husband had been killed and that the Nigerian government was covering up his death.

The lawyer of the IPOB leader, Ifeanyi Ejiofor, said on Tuesday that he did not know whether his client was dead or alive and had not seen him since the alleged raid on Kanu’s home in Umuahia, southeast Nigeria, the BBC reported.

There were gunshots on a wall at the family home of Indigenous People of Biafra (IPOB) leader Nnamdi Kanu features a painted flag of the former Republic of Biafra and holes purportedly caused by bullets, in the city of Umuahia, southeastern Nigeria, on September 27.

The Nigerian military denied that the raid—which Kanu’s supporters say happened on September 14 and resulted in some 20 IPOB members being shot dead—ever took place and have said that Kanu is not in their custody.

The trial has been adjourned until November 20, with the court ordering Kanu’s team to produce him on that date, but the IPOB leader is yet to be found.
