Nairobi attack: 1 gunman was son of Kenyan military officer, Investigation claims

Recent investigation reports behind the terror attack at a hotel and shopping complex reveal that one of the extremists was a son of a Kenyan military officer.

A senior police official says that the military officer was summoned for questioning about when he last saw his son and any other details. The police official spoke on Thursday, January 17 on condition of anonymity because he is not authorized to speak to the media.

The Daily Nation, a Kenyan newspaper, on Friday, January 18 identified the attacker as Ali Salim Gichunge and said his father is a sergeant with the Kenya Defence Forces. The newspaper says Gichunge's mother was arrested and taken to Nairobi for questioning.

Kenyan authorities say 20 civilians, one police officer and five attackers died in the assault Tuesday. The al-Shabaab extremist group claimed responsibility.
