It's a sad state of affairs, you can't even tell which side is the greater evil in all of this, gaalo on both sides and both sides are Muslims.
It reminds when the Jewish tribes in Medina went to war with each other and each side used at that time the Mushrikeen of Awz and Kazraj against each other instead of making dawah to them.
All this for miserly wordily gains and there punishment for this was perpetual humiliation in this life and a lasting punishment in the next.
The same scenario is being played out here, the only difference is that the Jews were not known as fighters but were at least the financiers, but in this case the Somali's on both sides are just mere pawns.
2:84
And [recall] when We took your covenant, [saying], "Do not shed each other's blood or evict one another from your homes." Then you acknowledged [this] while you were witnessing
2:85
Then, you are those [same ones who are] killing one another and evicting a party of your people from their homes, cooperating against them in sin and aggression. And if they come to you as captives, you ransom them, although their eviction was forbidden to you. So do you believe in part of the Scripture and disbelieve in part? Then what is the recompense for those who do that among you except disgrace in worldly life; and on the Day of Resurrection they will be sent back to the severest of punishment. And Allah is not unaware of what you do
2:86
Those are the ones who have bought the life of this world [in exchange] for the Hereafter, so the punishment will not be lightened for them, nor will they be aided.
