A faithful attends a special Easter mass at the Holy Family Basilica Catholic Church for the victims of the Garissa University attack in Kenya's capital Nairobi April 5, 2015. The son of a Kenyan government official was one of the masked gunmen who killed nearly 150 at a university last week, the interior ministry said on Sunday, as Kenyan churches hired armed guards to protect their Easter congregations.
