I have heard they have a long running conflict that goes back to millenia and it has never been settled. Both the Somali Issa and Afars claim their most fearsome tribesmen live in that area
The Afars tried to make an alliance with the Gadabursi because we are the only clan who know how to deal with the Isse. The Afars cannot atch the Isse in strength.
Its known that its Djiboutis ambition that Issa control the Afar valley and they do help their tribes men.
Afar lost a lot of territory but Issas do not have access to the river yet.
The reason is no Ethio government can afford somalis controlling the Asab-Addis road.
they let win Issa in the wild desert, but when they come closer to the strategic part they drive them back.
