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.
Mr Mahama said: “We must find a way to act together to share information, to synchronise our strategies, to pool our resources in order to rid the entire African continent of terrorism.
“We cannot stand by silently, idly waiting for the international community to intervene on our behalf.”
He said the crisis over Boko Haram was “increasingly getting to the point where probably a regional or a multinational force is coming into consideration”.
Earlier, Cameroon said Chad was sending a large contingent of troops to help it fight incursions by Boko Haram.
It came three days after Cameroon said it had killed 143 Boko Haram militants who had attacked one of its army bases at Kolofata near the Nigerian border.
It was the first major attack on Cameroon since Boko Haram threatened the country’s leader in a video posted online earlier this month.
