Human rights activists are calling for picketing of an African Union summit to protest a visit to Nigeria by indicted Sudanese leader Omar al-Bashir.

A diplomat at Sudan's embassy says al-Bashir, indicted in 2009 by the International Criminal Court for genocide in Darfur, is to arrive in the Nigerian capital of Abuja at 5 p.m. (1600 GMT) Sunday.

Chino Obiagwu says his Nigerian Coalition for the ICC is preparing to go to court Monday to demand Nigeria arrest al-Bashir. He says it is "Nigeria's obligation" as a member of the European-based court. The African Union has urged its 53 member states not to arrest al-Bashir. Some Africans accuse the court of racism in targeting Africans.

Obiagwu Sunday urged people to picket the AU health summit scheduled Monday and Tuesday.
