Mass antiwar protests in London

President George Bush welcomed Queen Elizabeth II to the residence of the U.S. ambassador for dinner Thursday evening, concluding his state visit to Britain. A few hours earlier, antiwar demonstrators protesting Bush's trip to London toppled an effigy of him in Trafalgar Square, mocking the toppling of a statue of Saddam Hussein by U.S. troops after they marched into Baghdad back in April. "Our message is quite simply, 'Go home, Bush,'" said one speaker at the protest, which police said drew between 100,000 and 110,000 people. Earlier Thursday, Bush's visit to Prime Minister Tony Blair's official residence, No. 10 Downing Street, took on a somber tone with the news that terrorist bombs had ripped through a British consulate and bank building in Istanbul, Turkey, killing at least 27 people, including Britain's consul general. At a joint news conference, both leaders said the attacks demonstrated the need to remain resolute in standing up to terrorists.
