This is actually Vigilantes and the Nigerian Army that are being accused of this. It is hard to balance civil rights when confronting enemies such as Boko Haram.
** Summary execution, beheading, amputation claims in Boko Haram fight **
Kano (Nigeria) (AFP) - Nigerian troops have been accused of killing 16 Boko Haram suspects, raising fresh concerns about the conduct of the military and the civilians supporting the battle against the militant group.
Earlier, vigilantes claimed to have beheaded dozens of Islamist fighters in the country’s far northeast.
Boko Haram, meanwhile, is reported to have begun enforcing strict Islamic law by amputating the hands of thieves and razing churches in a captured town it renamed as part of its self-styled caliphate.
