Kenya: 10 People Die in Retaliatory Tribal Attack Officials in Kenya say 10 people have been killed in a retaliatory tribal attack. Kenya's Red Cross said five children were among those killed in the 7 a.m. attack near the Tana River on Thursday. Witnesses said more than 100 people launched the attack, and that many were armed with guns, spears and bows and arrows. Thursday's attack appears to be in retaliation for an attack on Wednesday in the Tana River area, in eastern Kenya, in which at least seven people were killed. Authorities say there is deep-rooted hatred between the Pokomo and Orma communities, who have been fighting for years. Police say they are investigating politicians, businessmen and powerbrokers for instigating the violence.
