Nigerian President Muhammadu Buhari on Sunday appealed for "peace" as authorities struggled to halt looting across the country, the latest in a wave of unrest sweeping Africa's most populous nation.
A statement from the presidency said Buhari backed a judicial inquiry in Lagos "to give justice to peaceful protesters who lost their lives, security men who were murdered" and those who lost property in days of violence.
The leader "appealed to the people all over the country to maintain peace and brotherhood as the machinery of the government and the wheel of justice turn against the perpetrators", it said.
