Kenyanske myndigheter mener de har identifisert de fire som angrep Westgate-senteret. En av dem er norsk-somalier.

Myndighetene mener de bodde i Nairobi i flere måneder mens de planla angrepet.

The attackers behind the siege of the Westgate shopping mall that left more than 60 people dead in September had been living in Nairobi and plotted the attack for several months, a Western official briefed on the investigation said Monday. Kenyan officials say they believe they have determined the identities of the four attackers who stormed the mall. All four of the men are Somali citizens, though one of the men, previously identified as Hassan Abdi Dhuhulow, grew up in Norway. Remains recovered from the mall that are believed to be those of the attackers are still undergoing forensic testing at an F.B.I. laboratory, the Western official said. A Somali militant group, theShabab, claimed responsibility for the attack. The four men entered the country from Somalia in June and lived in Nairobi’s Somali neighborhood, Eastleigh. Kenyan authorities initially said that up to 15 assailants were involved in the attack, but only four are visible on mall surveillance tapes. Four other men have been charged as accomplices.
