Story highlights Photographer James Oatway captured a violent attack that resulted in death of a Mozambican in South Africa

Seven people have been killed in recent violence against poorer immigrants, many from South Africa's neighbors

Johannesburg (CNN) He checked the series of stills on his camera. It was then that photographer James Oatway realized the entire attack had taken less than two minutes.

It was the morning after a night of unrest in Johannesburg's Alexandra Township that saw foreign-owned shops looted and destroyed.

Mozambican Emmanuel Sithole was walking down a street when four South Africans surrounded him. Sithole pleaded for mercy, but it was already too late. The attackers bludgeoned him with a wrench, stabbed him with knives, all in broad daylight. And Oatway had captured it all on his camera.

"They looked like hardened thugs, just by their intensity, the way they moved, the expressions on their faces," Oatway told CNN. "They wanted one thing and that was to kill Emmanuel. They wanted his blood and nothing was going to stop them from doing that."

"When the attack started I was 20 meters away, but at one point I was four or five meters away," he said. "I did think that maybe they would leave him alone."

Later, Zwelithini said he had not called for a war on immigrants: "This war I am calling for today is to protect everyone of foreign origin in this country irrespective of which country they are from."

"And I'm extremely angry, angry with the men that did this and ultimately I'm upset that our efforts weren't successful in saving Emmanuel's life." Hide Caption 9 of 9

Oatway says he tried to get as close as possible, conscious that the attackers were aware of his presence. "When the attack started I was 20 meters (65 feet) away, but at one point I was 4 or 5 meters away," he said. "I did think that maybe they would leave him alone."
