Why Nigeria has not defeated Boko Haram (http://www.theinfostride.com/news/world-africa-27396702)
(http://news.bbcimg.co.uk/media/images/75306000/jpg/_75306515_line976.jpg) Recently they have carried out raids into neighbouring Cameroon and this week Boko Haram's leader said his fighters had carried out the brutal attacks on the Nigerian town of Baga.
He said they had seized enough weapons from Baga's military base to "annihilate Nigeria".
Some reports said that as many as 2,000 people died in Baga but Nigeria's government has disputed this, putting the toll at 150.
Mr Dasuki told the BBC's Newsday programme the fact that so many of the country's security sources had been deployed to deal with the militants showed how seriously the situation was being taken.

Mr Dasuki has dismissed such criticisms, saying there were "cowards" within the armed forces who hampered the campaign against the insurgents.
When asked if Nigeria needed outside help, he said "No", before saying it was an option to involve UN and AU forces, but regional partners were best placed to deal with the problem,
Nigerian soldiers currently make up the bulk of UN peacekeepers deployed to Africa, the security chief has said.
Correspondents say so far the regional fight against Boko Haram has been ineffectual.
Efforts to form a multinational force involving Nigeria, Niger, Chad and Cameroon have floundered.
However, following a meeting this week it was agreed that they would seek UN backing for the force - and move the headquarters from the captured town of Baga to Chad's capital, N'Djamena.
Over the weekend, Chadian soldiers deployed to Cameroon's border with Nigeria to help secure the porous border.
