In Cameroon, insurgents liberated kidnapped aid workers.
Armed men came into their homes and abducted the relief workers in February when they were organizing humanitarian aid activities in the northern town of Fotokol.

Five Médecins Sans Frontières (MSF) relief workers who were kidnapped in northern Cameroon and held captive for almost a month have been released.
The group was released in Nigeria, a neighboring country.
A Franco-Ivorian, a Senegalese, a Chadian, and two Cameroonian security officers are among them.
They are now "safe and sound," according to the charity.

MSF has not revealed the circumstances of their release, and it is still unknown who kidnapped them.
However, the extremist group Boko Haram and its offshoot, the Islamic State West Africa Province, have been wreaking havoc in the region.
Since its inception in 2009, the Islamist insurgency in the Sahel area has killed hundreds of thousands of people and displaced millions in many nations.
