Boko Haram crisis: 'Thousands have died in Nigeria army custody', says Amnesty

Amnesty International has released a damning report on the Nigerian military, naming officers that it says should be investigated for war crimes and crimes against humanity.

It accuses several senior commanders of being responsible for the deaths of thousands of young men as part of the fight against Boko Haram militants.

Amnesty says that over the last four years, more than 7,000 young men and boys died in military custody - in some cases, from deliberate starvation.
