New York, Jan 16 :Six years after the devastating earthquake that killed more than 200,000 people and left at least 1.5 million homeless, the United Nations is underlining that humanitarian action has achieved significant results, but that the situation has been deteriorating since June. Despite the progress achieved to date, there are still nearly 60,000 people living in IDP [internally displaced persons] camps in vulnerable situations and in need of humanitarian assistance and durable solutions, said Enzo di Taranto, Head of the United Nations Office for the Coordination of Humanitarian Affairs in Haiti.
