PORT-AU-PRINCE, Haiti (AP) - Hungry, haggard survivors clamored for food and water Saturday as donors squabbled over how to get aid into Haiti and rescuers waged an increasingly improbable battle to free the dying before they become the dead.
Haiti's government alone has already recovered 20,000 bodies - not counting those recovered by independent agencies or relatives themselves, Prime Minister Jean-Max Bellerive told The Associated Press. He said a final toll of 100,000 dead would "seem to be the minimum."
There were growing signs that foreign aid and rescue workers were getting to the people most in need - even those buried deep beneath collapsed buildings - while others struggled to cope with the countless bodies still left on the streets.
Crowds of Haitians thronged around foreign workers shoveling through piles of wreckage at shattered buildings throughout the city, using sniffer dogs, shovels and in some cases heavy earth-moving equipment.
Searchers poked a camera on a wire thorough a hole at the collapsed Hotel Montana and spotted three people who were still alive, and they heard the voice of a woman speaking French, said Ecuadorian Red Cross worker David Betancourt.
In Washington, President Barack Obama joined with his predecessors George W. Bush and Bill Clinton to appeal for donations to help Haiti and he sent Secretary of State Hillary Rodham Clinton to the Caribbean nation.
"We stand united with the people of Haiti, who have shown such incredible resilience, and we will help them to recover and to rebuild," Obama vowed.
Bellerive said an estimated 300,000 people are living on the streets in port-au-Prince and "Getting them water, and food, and a shelter is our top priority."
The U.S. military operating Haiti's damaged main airport said it can now handle 90 flights a day, but that wasn't enough to cope with all the planes sent by foreign donors and governments circling overhead in hopes of winning one of the few spots available on the tarmac.
France's Cooperation Minister Alain Joyandet told The Associated Press that he had filed an official complaint to the U.S. government after two French planes, one carrying a field hospital, were denied permission to land.
A plane carrying the prime ministers of two Caribbean nations also was forced to turn back late Friday due to a lack of space at the airport, the Caricom trade bloc announced.
Haitian President Rene Preval urged donors to avoid arguments.
"This is an extremely difficult situation. We must keep our cool to do coordination and not to throw accusations at each other," Preval said after emerging from a meeting with donor groups and nations at a dilapidated police station that serves as his temporary headquarters.
With the National Palace and many ministries destroyed, Preval meets with ministers in the open air in a circle of plastic chairs.
On a street in the heavily damaged downtown area, the spade of a massive bulldozer quickly filled up with dead bodies headed for a morgue and immediate burial. Haiti's Prime Minister Jean-Max Bellerive told AP that disposing of bodies had become crucial.
"Sadly, we have to bring everybody to mass graves because we are racing against a possible epidemic," told AP. Haitians already have been piling bodies and burning them.
Many in the city have painted toothpaste around their nostrils and beg passers-by for surgical masks to cut the smell.
The U.S. Southern Command said it now has 24 helicopters flying relief missions - many from warships off the coast - with 4,200 military personnel involved and 6,300 more due by Monday.
But with aid still scarce in many areas, there were scattered signs that the desperate - or the criminal - were taking things into their own hands.
A water delivery truck driver said he was attacked in one of the city's slums. There were reports of isolated looting as young men walked through downtown with machetes, and robbers reportedly shot one man whose body was left on the street.
An AP photographer saw one looter haul a corpse from a coffin at a city cemetery and then drive away with the box.
"I don't know how much longer we can hold out," said Dee Leahy, a lay missionary from St. Louis, Missouri, who was working with nuns handing out provisions from their small stockpile. "We need food, we need medical supplies, we need medicine, we need vitamins and we need painkillers. And we need it urgently."
U.N. spokeswoman Elisabeth Byrs said the disaster is the most challenging the U.N. has faced in terms of resources needed. She said there was so much damage to local government and infrastructure that is is harder for relief agencies to work than it was after the Asian tsuanami of 2004.
