PORT-AU-PRINCE: Rescue teams clawed through the rubble of Port-au-Prince for the fifth straight day today still dragging out earthquake survivors even as bodies piled up and the UN said it had never confronted such a disaster. Amid new anger over the relief operations, some Haitians fought for the rations that are getting through while others carried the injured on their backs or on carts to emergency hospitals. Another 12 people were rescued yesterday, UN officials said, but the true scale of the disaster is slowly beginning to emerge. Between 20,000 and 30,000 people died in the town of Leogane, west of the capital and the epicentre of the magnitude 7.0 quake which struck on Tuesday, according to UN officials. The Medecins Sans Frontiers (Doctors Without Borders) aid group opened an emergency hospital at Carrefour, a poor district near Leogane. MSF emergency coordinator Hans van Dillen said crowds arrived almost immediately. UN Office for the Coordination of Humanitarian Affairs spokeswoman Elisabeth Byrs told AFP that 12 more people were pulled out alive from debris yesterday, taking the total to more than 70 since the teams started working. “We don’t give up hope to find more survivors,” stressed Byrs. “The morale of the rescue team is very high despite the hardship.” Some 43 international teams comprising 1,739 rescue workers and 161 dogs have already scoured 60 percent of the worst affected areas hit by the quake. About 10,000 American troops are being sent to assist and secure the stricken areas. US military helicopters crews unloaded boxes of vital supplies as massive queues formed at distribution points where the UN World Food Programme handed out high-energy food.
