Names of Westgate attack mastermind revealed

According to Channel 4 News in UK the alleged leader of the Nairobi shopping mall attack was born a Christian in Kenya and is a former member of the country's special forces.
The number one Westgate attacker was named as Omar or Umayr, who is believed to have been killed in this week’s siege.
Omar was a Kenyan national, born to a Christian family from Nairobi. He converted to Islam and was also a former member of Kenya’s special forces.
Umayr is understood to have left Kenya for Somalia in 2005, where he joined the Kamboni militant Islamist group. Kamboni later joined with al-Shabaab.
The report said the second man is known as Khadhab, who is a Somali national who worked in an Islamic bookshop in the Nairobi suburb of Eastleigh. He was arrested and imprisoned in Somalia, and it is alleged he was tortured by the CIA while in custody there.

Somalia: Al-Shabab Finds Fighters Among Somali Youth in Minnesota
Nimco Ahmed, a Somali activist who works for the Minneapolis City Council, says the war and resettlement has fractured the traditional family structure.

"Most of our fathers are either not here or not in the country or dead pretty much. So not having a father figure for boys has been a struggle for us. And it is still a struggle for us," said Ahmed.

Ethiopia's invasion of Somalia in 2007 was viewed by some Somalis as a violation of Somali sovereignty even though the troops intervened at the request of the transitional Somali government and with the backing of the African Union and the U.S.

Using a mixture of religion, nationalism and what some say is deception, the Islamist militant group al-Shabab has recruited at least 20 Somali-Americans to fight against foreign troops in Somalia
