The Kenyan government held a memorial service to mark the 10th anniversary of the Westgate Mall siege when gunmen of the Somalia terror group Al-Shabaab stormed on 21 September 2013 the uptown shopping mall, killing at least 67 people and injuring more than 200 people in an attack that lasted four days.
