Drought and famine are forcing tens of thousands of Somalis to abandon their homes and seek assistance in the capital, Mogadishu, or neighboring countries. The U.N. World Food Program and other agencies say, however, the ongoing conflict in Somalia and actions by the militant group al-Shabab also are to blame for the growing migration. Aid workers at the Hagadera reception center in Kenya say the number of refugees has increased dramatically since June. The lack of food and water in many parts of Somalia is certainly the main reason so many Somalis are fleeing their homes. But Vincent Cochetel, the regional director for the United Nations refugee agency, said fighting and oppression also are causing people to head for the camps.
