Anger and despair mounted in quake-hit Haiti with rotting bodies littering the rubble-strewn streets and little sign of international aid as the Red Cross said up to 50,000 people may be dead. The stench of death hung over the capital Port-au-Prince as residents, still clawing through rubble in the hunt for survivors, faced another night in the open, traumatised by aftershocks triggered by Tuesday's massive earthquake. Across the capital frustrated Haitians dug with their hands through mountains of concrete and rubble, their exhausting efforts punctuated by the intermittent screams and moans of those buried below.<br/><br/>Despite the launch of a massive foreign aid operation, there is no sign of heavy lifting equipment among the ruins as tons of material and badly needed supplies clogged up the international airport. Some 7,000 dead had already been buried by yesterday, Peruvian Prime Minister Velasquez Quesquen said from Port-au-Prince, after Haitian officials warned the overall death toll may top 100,000. The officials said, up to three million people, one-third of Haiti's long-suffering population were affected. Sporadic gunshots were heard, and witnesses said there had already been some looting in a city that is all too familiar with bloodshed and natural disasters.<br/><br/>The USS Carl Vinson, a giant nuclear-powered aircraft carrier, was expected to drop anchor off the stricken nation today. In Port-au-Prince, flights jostled for space on the small airport's tarmac and single runway as aid poured in from around the world. Secretary of State Hillary Clinton and Defence Secretary Robert Gates cancelled foreign trips to help coordinate the US effort, which includes 100 million dollars in immediate assistance and the deployment of over 5,000 US troops, plus three amphibious ships and several Coast Guard cutters. Meanwhile, former Haitian president Jean Bertrand Aristide, exiled to South Africa since he was ousted in 2004, said he was ready to return to help rebuild his country.<br/><br/>Meanwhile, The United Nations said today that an estimated Three Lakh people have been left homeless by the devastating earthquake in Haiti. A helicopter assessment by the UN mission in Haiti found that some areas suffered 50 per cent destruction. Elisabeth Byrs, spokeswoman of the UN Office for the Coordination of Humanitarian Affairs, OCHA, said, some 35 lakh people live in areas hit by strong shaking from the 7.0-magnitude earthquake that flattened much of Haitian capital Port-au-Prince this week. Besides Port-au-Prince, Jacmel, an area south of the capital and Carrefour, a suburb close to the capital, are also affected. The agency stressed that search and rescue assistance remains the top priority, while food, clean water and sanitation are also critical.
