Thousands killed as South Sudan slides towards civil war

why do these people do this ? how many more centuries i wonder will mankind be so intolerant of each other.

This is Africa. Still a tribal continent.

Maybe Madonna & Brad & Angelina can go and adopt some more kids.

Send in the marines!

So Africa is the only tribal continent on the face of the earth?? Sorry, the last time I checked Arab countries,etc...also had plenty of tribal violence. Just look at Iraq, Lybia, Syria etc...
