Eyewitnesses say Somali police shot one person dead and wounded two at a distribution of food aid in the capital.
Witness Abdulkhadir Abdi says police fired to control unruly crowds at a camp for displaced families in Mogadishu's Wadajir district.
Witness Ali Muhummad says one man was killed and two others wounded in Thursday's incident. He says the police also looted some of the food themselves. Many police have not been paid in months and the weak U.N.-backed government is unable to control its own security forces. Fatal shootings and looting at food distributions are common.
Two people were killed in separate incidents within the past week at distributions by Turkish aid agencies.
The U.N. declared parts of war-ravaged Somalia famine zones in July.
