Nigerian police and military units carried out extrajudicial killings last year in the aftermath of clashes with members of a Muslim group in the north of the country, footage obtained by Al Jazeera appears to confirm.

An estimated 1,000 people were killed as Nigerian government forces fought Boko Haram in Borno, Yobe, Kano and Bauchi states in July and August of 2009.

But the footage obtained by Al Jazeera shows that many of the deaths occurred once the fighting was over.

Elements of the police and army staged a follow-up operation in which house-to-house searches were conducted and individuals were apparently selected at random and taken to a police station.
