The newly released images from the mall's security cameras show four men armed with AK-47 assault rifles cold-bloodedly firing on defenseless shoppers. At one point, a gunman is seen shooting a man trying to hide behind a statue of an elephant. Bleeding profusely, but still alive, the man squirms. Then another gunman comes back and finishes him off.
In other scenes, terrified shoppers and employees scramble for safety, some scuttling like crabs, as tracer bullets flash overhead.
Authorities so far have been unable to identify any of the assailants from the bodies pulled from the rubble of the mall, where a raging inferno tore through its main department store and a roof parking lot collapsed.
Charred human remains recovered Thursday were awaiting forensic tests today to determine if they are attackers. They filled two plastic containers measuring a foot wide and a foot across, and were recovered, along with four AK-47s, from a section of the mall that collapsed as security forces battled the terrorists, authorities said Friday.
Johansen Oduor, the chief Kenyan government pathologist, said he doesn't know if the remains were those of two bodies or three because the remains were sealed and he hasn't seen them yet.
Al-Shabab claimed responsibility for the Sept. 21 attack, saying it was in retaliation for Kenya sending troops into Somalia to go after the extremists. Kenyan officials initially said 10 to 15 gunmen carried it out, but the security camera video shows only four. A police official said three suspects are in custody, although none of them took direct part in the attack.
Besides the AK-47s, 11 magazines of ammunition -- all apparently used by the attackers -- also were found in the rubble, a security official said. A rocket-propelled grenade, likely from Kenyan security forces, also was recovered.
Somali authorities might have had Dhuhulow in their grasp earlier this year, when a man with the same name was arrested in Mogadishu in connection to the slaying of a Somali journalist. A Somali court released the man in March for lack of evidence.
Meanwhile, in Larvik, those who knew Dhuhulow said they are shocked that someone who grew up in their midst has been identified as a suspect in the Nairobi mall attack.
Hassan described the community as a "wonderful, multicultural" place with a strong track record of peaceful integration. "The language school here, where foreigners come to learn Norwegian, is brilliant," he said. "It is teaching other communities how to do it."
Robert Rognli, principal of Thor Heyerdahl High School, which Dhuhulow attended from 2006-09, described Larvik as a "typical Norwegian town with a typical Norwegian community spirit."
A former high school classmate of Dhuhulow's said it is hard to believe the teen she once knew could have carried out such an attack.
"The video I saw looks a lot like him, but it's difficult to see," said the woman, who didn't want her name used because she was uncomfortable being associated with a terrorism investigation.
"He was a quiet guy," she said. "He was very committed to his religion, but not extreme. He brought a prayer mat to school."
