Kenya is planning to close the world’s largest refugee camp, which it says poses a security threat that could lead to terrorist attacks. An estimated 330,000 refugees will be affected when the Dadaab camp in northeast Kenya is shut down. Most refugees there are from Somalia who escaped conflict in their country. Kenya’s government announced plans to close the camp “within the shortest time possible.” But the United Nations and international human rights groups have criticized the move. The U.N. refugee agency urged Kenya this week to reconsider its decision. The agency said in a statement that closing the camp would have “devastating consequences.” It urged the government to “avoid taking any action that might be at odds with its international obligations.” Kenya’s Interior Minister, Joseph Nkaissery, said at a news conference Wednesday that the camp threatens Kenya’s security. He said the government believes the camp harbors extremists from Somalia’s Islamic al-Shabab group.
