The Kenyan government has ordered refugees living in its urban areas back to their designated camps.

The move, targetted at the mainly Somali refugee population, comes after at least six people were killed in an attack on a church in the coastal city of Mombasa on Sunday. The attackers were not identified but there have been a number of attacks by the Somali group Al Shabab in recent years.
