Ghana's President John Mahama has said he and other African leaders will discuss plans next week to "deal permanently" with Boko Haram militants.
He said he wanted African Union (AU) countries to produce a "specific plan of action" for tackling the Nigeria-based Islamist group collectively.
"This has to end. We have to make this terror end," he said.
Boko Haram has seized control of many towns and villages in north-east Nigeria in a six-year insurgency.
It has also begun threatening Nigeria's neighbours and earlier this week launched a raid on a military base in northern Cameroon.
