Ethnic tensions have been simmering in Kenya after the September 10 massacre at Kilelengwani - carried out by ethnic Pokomo against the Orma tribe - followed a string of tit-for-tat attacks between the agriculturalist and pastoralist communities.
More than 110 people have been killed since late August in Kenya's Tana River region, about 420km from the capital Nairobi. Some 6,000 people have been displaced, according to Human Rights Watch.
Tensions regularly flare between the two groups during the dry season, when Orma bring their cattle to graze on Pokomo land.
But the conflicting livelihoods of two communities no longer sufficiently explains the level of violence. The attackers are better organised and display unprecedented levels of brutality, indiscriminately killing women and children.
