Human rights groups are accusing Nigeria's Joint Task Force of killing civilians in its fight against the armed group Boko Haram.
The group has claimed responsibility for killing thousands of people since it was founded in 2002.
Boko Haram, which means "Western education is forbidden", says it wants to create an Islamic state in Muslim-dominated northern Nigeria.
The US has put Boko Haram and its leader Abubakar Shekau on its list of terror organisations.
Al Jazeera's Yvonne Ndege reports from the northern city of Maiduguri, where local people say government forces are killing civilians.
