Babies and children are among more than 100 people to have died in detention this year in a military barracks in northeast Nigeria where suspected Boko Haram members are being held, often without any evidence, Amnesty International said on Wednesday.

Around 1,200 people, 1 in 10 of whom are children, are being detained at Giwa barracks in the city of Maiduguri, where they are kept in dirty, overcrowded cells without enough food or water and denied access to legal aid or a trial, Amnesty said.

Some 150 people, including seven young children and four babies, have died this year in Giwa barracks, many from disease, hunger, dehydration and gunshots wounds, according to Amnesty.
