Dadaab, Kenya: A giant refugee camp Somalis call home

The UN is preparing to carry out a survey in the world's largest refugee camp, Dadaab in Northern Kenya, to find out how many of the hundreds of thousands of Somalis who live there would be prepared to go home.
But, as Gabriel Gatehouse explains, very few residents are likely to say they want to return to their country, despite concerns about extremism within the camp.
Kenya believes that some individuals from the camp were involved in planning the attack on the Westgate shopping mall in Nairobi in September, in which more than 60 people were killed.
The Somali militant Islamist group al-Shabab claimed it carried out the attack and four men charged in connection with the siege are said to be of Somali origin.
