Here's more evidence from the AP:
The U.N. said Thursday it has temporarily pulled international staff out of parts of Somalia controlled by Islamic radicals after receiving written threats.
The U.N. said the threats came shortly after the Sept. 17 shooting deaths of an Italian nun and her bodyguard in the capital, Mogadishu, which was seized by an Islamic militia in June. Somalia's president narrowly escaped a suicide car bombing a day later in Baidoa, the seat of the weak U.N.-backed governmentâ€¦.
The Islamic movement controls much of Somalia's south. Its strict interpretation of Islam has raised fears of rule like that of Afghanistan's ousted Taliban regime.
The United States has accused the group of sheltering suspects in the 1998 al-Qaida bombings of U.S. embassies in Kenya and Tanzania. Bin Laden has said Somalia is a battleground in his war on the West.
