Hassan Mohammed Ali of Somalia, head of United Nations High Commissioner for Refugees (UNHCR) office in Mogadishu, gestures upon his arrival at the airport in Somalia's capital Mogadishu August 28, 2008. Kidnappers freed Ali on Wednesday but rising insecurity forced Medecins Sans Frontieres (MSF) to close a clinic in Mogadishu that provided essential health care to hundreds of women and children.
