Boko Haram affected areas

[…] More than 65,000 people have been killed since the fight against the insurgents started. Also, no fewer than 2.1 million displaced persons have been settled in many camps across the country.

The militaries of Cameroon, Chad, Niger and Nigeria have hailed the success of a joint security operation they say has freed 4,500 civilians and killed more than 800 militants since late March.

A Nigerian military commander said at least 51,000 Boko Haram terrorists and their families have surrendered in the country's northeast in just the first three months of this year.

A joint military force from Nigeria, Niger and Cameroon said Sunday it had killed more than 100 Islamist insurgents, including 10 commanders, in the past few weeks, as it intensifies a ground and air offensive in the Lake Chad region.

While the current crisis in the Lake Chad region is often framed by the violence perpetrated by Boko Haram, other factors have converged and exacerbated the crisis.

The MNJTF, headquarter in N’Damena, Chad, is a combined multinational formation, comprising units, mostly military, from Benin, Cameroon, Chad, Niger, and Nigeria.

Authorities say they’re the latest among hundreds of the militant Islamists who have been defecting since May, when the group's leader was killed. Cameroon plans to deport the former fighters as the influx has overwhelmed rehabilitation centers along the border.

Cameroonian authorities said they are overwhelmed by the number of militants fleeing the extremist group Boko Haram. The National Committee for Disarmament, Demobilization and Reintegration, or the DDR, a center set up by the government, hosts about 750 former militants in Meri, a town on the northern border with Nigeria.

The toll, given by (UNDP) in a new study on the war and its impact on livelihoods, is 10 times higher than previous estimates of about 35,000 based only on those killed in fighting in Nigeria since the conflict's start 12 years ago. 

Jihadists have killed 35 people, including five troops and 15 militiamen, in two attacks in Nigeria’s troubled northern Borno state. … Islamic State-aligned militants have intensified attacks on army camps in recent weeks as part of a decade-long insurgency that has killed 36,000 people and forced more than two million to flee their homes.
