African leaders meeting in Paris have agreed to wage “war” on Nigeria’s Boko Haram Islamic militants.

President Hollande of France, who hosted the summit, said regional powers had pledged to share intelligence and co-ordinate action against the group.

Last month it abducted 223 schoolgirls in north-eastern Nigeria, where it is based. Fresh attacks were reported in Nigeria and Cameroon overnight.

Thousands of people have been killed by Boko Haram in recent years.

The Paris summit brought together President Francois Hollande, Nigeria’s Goodluck Jonathan, and their counterparts from Benin, Cameroon, Niger and Chad.

Afterwards, Mr Hollande said participants had agreed on a “global and regional action plan”.

He said this involved “co-ordinating intelligence, sharing information... border surveillance, a military presence notably around Lake Chad and the capacity to intervene in case of danger”.

Cameroon’s President Paul Biya said: “We are here to declare war on Boko Haram”. Idriss Deby of Chad said it would be “total war”.

Earlier, Mr Hollande called Boko Haram a “major threat to West and Central Africa”, and said it had links with al-Qaeda’s North-African arm and “other terrorist organisations”.
