Why are the cousins fighting?
Tharaka seem to be like Mbeeres - half kambas?
Basically its Imenti vs tharaka border issues. All along Tharaka border its fluid as they accuse,Tigania,Igembe,Imenti,Mwimbi and Chuka of encroaching on their land. Their is some true in this,so basically all Meru subtribes and clans are very territorial where I come from there are clan wars and so on. Thats why you find Meru is very ethnically homogeneous to almost 100% in rural areas you can't find a mukabila like you do in other areas and that's why its also easy to cook IEBC kura as no one will raise a voice or snitch.
