The authorities in Nigeria have ordered the arrest of the spokesman of the country’s main pro-Iranian Shia group.
The Islamic Movement in Nigeria (IMN) was banned last week by the governor of the northern Kaduna state, where most of its followers are based.
The spokesman, Ibrahim Moussa, told the BBC he would not hand himself in.
Last year, about 350 members of the group were killed during clashes with the army.
Its leader, Ibrahim Zakzaky, remains in detention. The IMN says about 30 of its members have been arrested in the past few days.
