Rights group says Saudi Arabia border guards fired on and killed hundreds of Ethiopian migrants

Border guards in Saudi Arabia have fired machine guns and launched mortars at Ethiopians trying to cross into the kingdom from Yemen, likely killing hundreds of the unarmed migrants in recent years, Human Rights Watch said in a report released Monday. The United Nations has already questioned Saudi Arabia about its troops opening fire on the migrants in an escalating pattern of attacks along its southern border with war-torn Yemen. Saudi officials did not respond to requests for comment from The Associated Press, but has previously denied its troops killed migrants.
