Conflict between Christians and Muslims flared in late February in and around Kaduna City and in the southeastern cities of Aba and Onitsha. The violence stems from state government attempts to impose sharia, or Islamic law. Roadblocks were reported on the main road between Aba and Port Harcourt. Travel with caution in these areas, and follow local press reports for current updates. Further violence that occurred March 3-5 in the university town of Ife and nearby Modakeke in the Yoruba heartland was over land disputes and unrelated to the religious violence.
