Kenya's military spokesman confirmed the names of the four attackers implicated in the four-day-long siege at the Westgate Mall,which killed more than 60 people last month. Major Emmanuel Chirchir confirmed that the attackers are Abu Baara al-Sudani,Omar Nabhan,Khattab al-Kene and Umayr. He told The Associated Press: I confirm those are the names of the terrorist. Little is known about their identity. Matt Bryden,the former head of the United Nations Monitoring Group on Somalia,said via email that al-Kene and Umayr are known members of al-Hijra,a Kenyan extremist group affiliated with al-Shabab. He added that Nabhan may be a relative of Saleh Ali Saleh Nabhan,who was the most-wanted al-Qaida operative in the region until he was killed in a 2009 strike led by Navy Seals.
