Desperate Haitians Await Aid Following Quake VOA News 15 January 2010 Victims in a Port-au-Prince park Photo: AP Earthquake survivors a a public park in downtown Port-au-Prince, 14 Jan 2010 Desperate Haitians have spent a third night in the streets of the capital, Port-au-Prince, waiting for promised aid that is slowly trickling in following Tuesday's devastating earthquake. The aircraft carrier USS Carl Vinson was expected to drop anchor off the Haiti coast Friday where it will serve as floating airport for helicopters carrying rescue teams and supplies. Troops and planeloads of desperately needed food and medicine from many countries began slowly arriving in Haiti Thursday after the worst earthquake in 200 years reduced the capital city to rubble. The aid flights, however, have swamped the main airport. Aid agency officials and workers say looting of food and other supplies has become an increasing problem as people become more desperate. Red Cross officials estimate that 45,000 to 50,000 people were killed in Tuesday's 7.0 magnitude earthquake, which flattened homes and government buildings, burying countless numbers of people. Bulldozers helped move some of the rubble, while some Haitians have been using bare hands to try to free those trapped in the debris. Sheet-draped recovered bodies lay rotting in the tropical heat Meanwhile, former Haitian President Former Jean-Bertrand Ariside, exiled in South Africa since 2004, told reporters in Johannesburg that is he ready to return to Haiti to help rebuild the country. On Thursday, U.S. President Barack Obama promised $100 million in new aid to support Haiti's recovery, adding that the relief effort under way will be one of the largest in recent U.S. history Planes carrying workers and supplies from the United States, Spain, China, Russia and other countries have arrived, while many more countries have promised aid. Roads are blocked, and water, electricity and telecommunications services have been severely disrupted, complicating relief efforts. But, the VOA correspondent in the area says people are sharing what they have and hoping the situation will improve. The headquarters of the United Nations mission in Haiti was among the buildings that collapsed as the ground shook Tuesday. The U.N. says at least 36 of its personnel were killed, while some 150 remain unaccounted for, including the head of the U.N. mission there, Hedi Annabi. U.N. Secretary-General Ban Ki-moon says the needs in Haiti are huge and immediate - above all, medical supplies, food, water, tents, shovels and heavy equipment. But he said that overall, security and public order are being maintained, and that U.N. peacekeepers are continuing to patrol and help the humanitarian effort. Of the 9,000 U.N. peacekeepers in Haiti, the 3,000 based in Port-au-Prince are clearing roads to assist search and rescue teams. Officials estimate that as many as three million people - one third of Haiti's population, may have been affected by the quake. Donations to aid organizations are pouring in, and the Red Cross has pledged $1 million to support relief operations. Haiti is the Western Hemisphere's poorest country.
