Officials investigating the Westgate Mall attack in Kenya now know the real names of all four gunmen.

A Western official said Monday that all four are ethnic Somali, and that none has been to the U.S. or U.K. Two names have been released. The official, who insisted on anonymity to discuss information not yet released, would not reveal the others. The FBI is analyzing the remains believed to be the attackers.

The four gunmen arrived in Kenya in June and were previously in Somalia. Officials know where the four lived in Nairobi and the gym they attended in Nairobi's Somali neighborhood, Eastleigh.

Kenyan officials say 67 people died in the September attack, but with some two dozen people unaccounted for, the official said the toll could rise.
