Conflict between Somali Islamists and interim government forces has escalated in recent days. The PBS NewsHour with Jim Lehrer interviewed Akwe Amosu, senior policy analyst for Africa at OSI-Washington, D.C., and Abdi Samatar, professor of geography at the University of Minnesota, about the reasons for the violence and the possibility of it enveloping the Horn of Africa region.

Video and a transcript of the segment are available on the PBS website at www.pbs.org/newshour/bb/africa/july-dec06/somalia_12-26.html.
