The detained leader of a pro-Iranian Shia group, Sheikh Zakzaky is reported to be partly paralysed, this is according to his lawyer.
Ibrahim Zakzaky, who leads the Islamic Movement in Nigeria (IMN), and his wife have been in detention since their home in Zaria was besieged by troops in December.
“The leader of the IMN now walks with a limp. The left eye of the leader of the IMN is completely damaged. The left hand has lost its motor function,” his lawyer Maxwell Kyon is quoted as saying.
Mr Zakzaky is also challenging his continued detention in an Abuja court, claiming 2bn naira ($10m; £7m) in damages, AFP reports.
