Nigeria killings caught on video
Nigerian police and military units carried out extra-judicial 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 only after 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.
'Shoot him in the chest'
In the video, a number of unarmed men are seen being made to lie down in the road outside a building before they are shot.
As one man is brought out to face death, one of the officers can be heard urging his colleague to "shoot him in the chest not the head - I want his hat".

Rights groups claim police killings
As the executions continue another man is told: "Sit properly we want to take your picture."
The shootings continue as a crowd gathers further up the street in front of the police station.
Voices can be heard saying: "No mercy, no mercy."
After the executions, the army officer who appears to have been in charge of the operation is seen to be handing over command to a senior police officer. Both men are clearly identified by the name tags on their chests.
The family of Baba Fugu Mohammed, a respected community leader, told Al Jazeera that he was among those put to death outside the police station.
"He was killed, he was killed, that's what we believe. He was shot by the police," one relative said.
Fugu Mohammed was the father-in-law of Mohammed Yusuf, the Boko Haram leader whose group had battled the police, but the two had become estranged.
His family said that he had come to help police restore order, but was shot.
'Killings of the innocent'
In the days following the clashes between the police and Boko Haram, the government, police and military repeatedly denied that civilians had been killed by their personnel.
