US Troops to Be Re-Deployed to Haiti VOA News 21 January 2010 Haitians gather for relief supplies Photo: AP U.S. soldiers work to organize earthquake survivors who gathered for disaster relief supplies in Port-au-Prince, 19 Jan 2010 U.S. military officials say an amphibious force of 4,000 sailors and Marines will be diverted from scheduled deployments elsewhere and sent to Haiti to assist in earthquake relief efforts. A similar unit began to deploy onshore west of the devastated capital, Port-au-Prince Tuesday. The new deployment will bring the number of U.S. forces being sent to Haiti to about 14,000. U.S. President Barack Obama told the ABC television Wednesday the United States cannot afford to ignore the trouble in Haiti. He also said the U.S. does not want its relief efforts to appear as if it is taking over the Caribbean country. Mr. Obama said he wants to make sure that when America projects its power around the world, it is not seen only when it is at war. A powerful aftershock jolted Haiti on Wednesday, sending panicked residents screaming into the streets and bringing down some buildings already ruined by last week's 7.0 magnitude earthquake. The 5.9 magnitude aftershock added to the trauma caused by the January 12 quake that devastated the capital,and surrounding areas, leaving hundreds of thousands dead or homeless. U.S. Secretary of State Hillary Clinton told reporters at the State Department that officials are closely monitoring the impact of the aftershock, which wrecked a pier that was to be used as a staging area for patients. The aftershock was felt on the U.S. Navy hospital ship, USNS Comfort, which reached Haiti early Wednesday and has begun accepting injured survivors for treatment. The United States also is sending a vessel designed to clear debris blocking the main port in Port-au-Prince. That debris has prevented larger ships with food and other vital supplies from making deliveries. Officials estimate the earthquake affected three million people in Haiti, about one-third of the population of the Western Hemisphere's poorest country. Some 200,000 people are believed to have been killed. Survivors are living in makeshift camps on streets littered with debris and decomposing bodies. Doctors are struggling to treat thousands of injured with limited resources. Some damaged buildings in the Haitian capital have been ransacked by people searching for supplies. U.S. troops have been providing security for food and water deliveries. About 3,500 additional U.N. security personnel are being sent to Haiti to help prevent looting. The World Food Program said it will try to get fresh aid to as many people as possible. But officials said relief efforts have been hampered by blocked roads, bureaucratic confusion and the collapse of local authority. Secretary Clinton Wednesday defended the U.S. relief efforts, saying it is "really remarkable" how much has been accomplished, given the challenges. Clinton said she will head to Montreal, Canada, next Monday to attend a conference on generating better coordination among countries providing disaster relief to Haiti, and laying groundwork for long-term recovery and reconstruction efforts. In Britain, Prime Minister Gordon Brown said he has spoken with President Obama about helping to reconstruct the shattered Haitian government. Britain is tripling its aid to Haiti, from $10 million to $30 million. .
