THE mystery thickens: was a Taliban 'guest' behind last fortnight's brutal blasts outside American missions in Africa? "How can a man living as a refugee in Afghanistan sponsor bomb explosions in distant Africa?" counters Mulla Mohammad Omar, founder of the four-year-old Taliban Islamic Movement. "I don't think Osama Bin Laden is behind the acts of terrorism in Kenya and Tanzania." In a telephonic interview with 바카라 from the movement's headquarters in Kandahar in southwestern Afghanistan, he pointed out that Bin Laden was a guest in Afghanistan and had come to the eastern city of Jalalabad before the city fell to the Taliban in September 1996.
