Nigerian President, Muhammadu Buhari has appealed for calm after at least ten people were killed in ethnic violence in the southern city of Ibadan.
In a tweet, Mr. Buhari called on religious and traditional leaders not to allow ethnic or religious groups to stoke hatred and violence against other groups.
He said his government will protect all religious and ethnic groups in Nigeria, whether majority or minority, in line with the responsibility under the constitution.
There have long been tensions in Nigeria between the mainly, Muslim north and the Christian-dominated south. Amnesty International has condemned the violence and called for those responsible for the killings to be brought to justice.
Police say they are investigating the attacks, but Amnesty International has called for an independent investigation.
