More than 1200 people have died from starvation and illness at an aid camp in northeastern Nigeria that houses people fleeing the Islamist militant group Boko Haram, medical charity Medecins Sans Frontieres says.
MSF says its team found 24,000 people, including 15,000 children, sheltering in the camp located on a hospital compound during a visit to Bama last month - its first trip to the city since it was wrested from Boko Haram's control in March 2015.
The city was part of an area around the size of Belgium that was held by Boko Haram for more than six months before being pushed out by the army.
MSF says "a catastrophic humanitarian emergency is currently unfolding" at the camp, adding that around a fifth of 800 children who underwent medical screening are acutely malnourished and that almost 500 children have died.
"We have been told that people including children there have starved to death," Ghada Hatim, MSF head of mission in Nigeria, said on Thursday.

"We were told that on certain days more than 30 people have died due to hunger and illness."
During its assessment, the MSF team counted 1233 graves near the camp that had been dug in the past year. It said 480 of these graves belonged to children.
More than 15,000 people have been killed and two million displaced in Nigeria and neighbouring Chad, Niger and Cameroon during Boko Haram's seven-year insurgency, in which the group has tried to create a state adhering to sharia Islamic law.
Nigeria's army, aided by troops from neighbouring countries, has recaptured most of the territory that was lost to the group. But the jihadist group, which last year pledged loyalty to Islamic State, still regularly stages suicide bombings.
