UN Secretary-General Ban Ki-moon on Saturday welcomed an African Union proposal to set up a regional five-nation force of 7 500 troops to fight Nigeria's Boko Haram Islamist militants.
Support for the initiative, announced at an African Union summit being held in Ethiopia's capital Addis Ababa, came hours after the Chadian military said three soldiers and 123 militants were killed in two days of fighting with a Chadian army contingent in northern Cameroon.
"I welcome the decision of the AU and regional countries to establish an MJTF (Multinational Joint Task Force) against Boko Haram," he told reporters on the sidelines of the summit.
'Unspeakable brutality'
"They have committed unspeakable brutality. Those terrorists should be addressed with a regional and international co-operation. Not a single country, even the regional countries, can handle this alone," he said. "The United Nations is ready to fully co-operate with the African Union."
