Nigeria: Violence in northern Nigeria kills at least 80

At least 80 people have been killed since Monday 18 June in clashes in northern Nigeria triggered by Islamists waging an insurgency against the government, figures from police and the Red Cross showed on Wednesday. The violence - some of which was sparked by church bombings over the last three Sundays - has heightened sectarian tensions in Africa's most populous country, which is evenly split between Christians and Muslims.
