Last July, Nigeria was racked by four days of violence between security forces and a militant group trying to impose strict Islamic law.
The group is called Boko Haram and the fighting was sparked by the arrest of several of its leaders. An estimated 700 people were killed.
Ever since, there has been concern that the security forces may have killed many innocent civilians.
This report from Mike Hanna of Al Jazeera English shows new video purportedly showing such attacks. Some of the images are graphic.
Daljit Dhaliwal spoke with Eric Guttschuss, a researcher with Human Rights Watch about the allegations. He says that the international community, including the United States, should be doing more to pressure the Nigerian government to ensure justice.
