Hundreds of supporters of the detained Nigerian Shia cleric, Sheikh Ibrahim Elzakzaky, have taken to the streets of the capital, Abuja to mark his 1000th day in detention and to push for his release.

The pro-Iranian Shia sect leader has been in detention since 2015; facing charges of homicide against army personnel. The charges are punishable by death.

The reportedly ailing cleric has denied the charges.

Nigerian officials accuse the group of wanting to foment an Iranian-style revolution and of being a "state within a state" - accusations the Islamic Movement of Nigeria (IMN) denies.
