Disputes - international:
Ethiopian forces invaded southern Somalia and routed Islamist Courts from Mogadishu in January 2007; "Somaliland" secessionists provide port facilities in Berbera to landlocked Ethiopia and have established commercial ties with other regional states; "Puntland" and "Somaliland" "governments" seek international support in their secessionist aspirations and overlapping border claims; the undemarcated former British administrative line has little meaning as a political separation to rival clans within Ethiopia's Ogaden and southern Somalia's Oromo region; Kenya works hard to prevent the clan and militia fighting in Somalia from spreading south across the border, which has long been open to nomadic pastoralists
