UN chief warns of crisis across Africa's Sahel

Secretary-General Ban Ki-moon is warning that political turmoil, terrorist activity, drug trafficking and arms smuggling are spilling over borders in Africa's Sahel region.
The U.N. chief told the U.N. Security Council on Monday that the crisis in Mali, where Islamist groups allied with al-Qaida now control the north, is part of "a sustained, systemic crisis across the entire Sahel region."
Ban said the challenges in Mali can't be addressed effectively unless the international community also confronts the challenges affecting the broader region.
Romano Prodi, the U.N. envoy for the Sahel, said he is working to organize global support to promote humanitarian aid and long-term development in the region, and to help reunite Mali.
He warned that the Sahel crisis may spread if it's not tackled in time.
