Islamist militants ambushed a shopping mall in Nairobi, Kenya, on Saturday killing more than 50 people and terrorizing the city. The siege was still taking place on Monday, as Kenyan forces tried to drive the militants out of the Westgate mall and save remaining hostages. Somalia's Al Shabab claimed responsibility for the deadliest attack in Kenya since 1998.
