A weekend of global anti-war protest has concluded in Sydney, with more than 200,000 Australians objecting to any U.S.-led war in Iraq. Prime Minister John Howard, whose cabinet has dispatched 2,000 troops toward the Gulf, said he was unswayed and remain "worried" about alleged Iraqi possession of chemical and biological weapons. Anti-war rallies on Saturday, in Africa, Europe and North America, drew in all between six and 11 million protestors - crowds not seen since the Vietnam war. Aside from mass rallies in London, Berlin, Rome and Athens, three million turned out in Spain to rebuke Prime Minister Jose Maria Aznar for his backing of the stance of U.S. President George W. Bush. In Calcutta, 10,000 protested; in Tokyo, 5,000, but elsewhere in Asia, protest was largely muted. A spokeswoman for Bush, whose cabinet has deployed 150,000 troops in the Gulf region, mainly Kuwait, said he saw force as a last resort.
