Tens of thousands of Sudanese marched peacefully through Khartoum on Thursday denouncing Israel's invasion of Gaza and the international community for alleged "complicity with the Zionist regime." The miles-long march started with fiery speeches and chanting of Islamic slogans in support of Gaza's Hamas rulers. When a speaker said the name of the US president, the crowd waved their shoes - a gesture evoking an Iraqi journalist who threw his shoes at George W. Bush during a recent Baghdad visit. The protesters also denounced Egypt's President Hosni Mubarak as a "hireling and cowardly" and handed in a protest note at the UN offices. Some carried green metal models of Kassam rockets.
