Nigeria's government has taken the controversial decision to ban a pro-Iranian Shia group, accusing it of unleashing violence and being an “enemy of the state”.
The Islamic Movement in Nigeria (IMN) is challenging the ban, arguing that it is a peaceful movement which has, in fact, borne the brunt of state-orchestrated violence.

Khomeini remains the group's main inspiration: IMN supporters first pledge allegiance to him at their gatherings, and then to their local leader, Sheikh Ibraheem Zakzaky. ..
