Official sources said on Wednesday in the Economic capital Douala that the meeting which is scheduled for June 12 is a follow-up to the May 17 summit held in Paris exclusively on the current insecurities in Nigeria.

The London ministerial meeting is to evaluate the progress so far made on the action plan of Paris. They will evaluate what Nigeria and its neighbouring countries - Chad, Niger, Benin and Cameroon - have done to fight these recent insurgencies.

This London summit comes at a time the Cameroon military is reported to have killed at least 60 Boko Haram members who crossed over from Nigeria seeking refuge recently. According to the national radio, the heavily-armed militants, reportedly killed in the village of Dabanga in far northern Cameroon, crossed over from Borno State in Nigeria.

However, mixed reactions seem to be trailing in Nigeria regarding Cameroon's killing of Boko Haram members. Nigeria’s former Minister of Petroleum Resources, Professor Tam David-West, has described the killing as an indictment on Nigeria which claimed to have declared total war on the sect members.

He told Daily Independent in Lagos that Nigeria has nothing to cheer about it because it is an indictment that would create more challenges for the country. “If you monitor the operations of the sect members, you find they launch more attacks on the people any time there is information disclosing the number the members killed by Nigerian security forces,” he said.

David-West warned that Nigeria might witness major attack as a result of the disclosure by Cameroonian government. But the former President of the Nigeria Bar Association (NBA) Ikeja branch, Barrister Onyekachi Ubani has described the action taken by Cameroon as a welcome development.
