PORT-AU-PRINCE, Haiti - Prayers of thanksgiving and cries for help rose from Haiti's huddled homeless Sunday, the sixth day of an epic humanitarian crisis that was straining the world's ability to respond and igniting flare-ups of violence amid the rubble of Port-au-Prince.
Haitian police struggled to scatter hundreds of stone-throwing looters in the city's Vieux Marche, or Old Market. Elsewhere downtown, amid the smoke from bonfires burning uncollected bodies, gunfire rang out and bands of machete-wielding young men roamed the streets, faces hidden by bandanas.
A leading aid group complained of skewed priorities and a supply bottleneck at the U.S.-controlled airport. The general in charge said the U.S. military was "working aggressively" to speed up deliveries.
Beside the ruins of the Port-Au-Prince cathedral, where the sun streamed through the shattered stained glass, the priest told his flock at their first Sunday mass since Tuesday's earthquake, "We are in the hands of God now."
But anger mounted hourly that other helping hands were slow in getting food and water to millions in need.
"The government is a joke. The UN is a joke," Jacqueline Thermiti, 71, said as she lay in the dust with dozens of dying elderly outside their destroyed nursing home. "We're a kilometre from the airport and we're going to die of hunger."
Water was delivered to more people around the capital, where an estimated 300,000 displaced were living outdoors. But food and medicine were still scarce.
The crippled city choked on the stench of death and shook with yet another aftershock Sunday. On the streets, people were still dying, people were on their knees praying for help, pregnant women were giving birth on the pavement, and the injured were showing up in wheelbarrows and on people's backs at hurriedly erected field hospitals. Authorities warned that looting and violence could spread.
At the Vieux Marche, police tried to disperse looters by driving trucks through the crowds, as hundreds scrambled over partly destroyed shops grabbing anything they could. As he ran from the scene with a big box of tampons, Love Zedouni shouted: "I've got no idea what this is, but I'm sure you can sell it."
Police used tear gas to scatter looters at street markets near the collapsed presidential palace. At the Cite Soleil slum, moments after police drove by, a reporter spotted a gunman stealing a bag of rice from a motorcycle rider.
"This is one of the most serious crises in decades," UN Secretary-General Ban Ki-moon said as he flew into the Haitian capital. "The damage, destruction and loss of life are just overwhelming."
A reliable death toll may be weeks away, but the Pan American Health Organization estimates 50,000 to 100,000 died in the 7.0-magnitude tremor, and Haitian officials believe the number is higher.
So far eight Canadians have been confirmed dead and more 1,115 others are unaccounted for. About 600 have been flown back to Canada.
Celebrating mass outside the once-proud pink-and-white cathedral, now a shell of rubble where a rotting body lay in the entrance, Rev. Eric Toussaint preached of thanksgiving to a small congregation of old women and other haggard survivors assembled under the open sky.
"Why give thanks to God? Because we are here," Toussaint said. "What happened is the will of God. We are in the hands of God now."
Mondesir Raymone, a 27-year-old single mother of two, was grateful. "We have survived by the grace of God," she said.
But others were angry.
"It's a catastrophe and it is God who has put this upon us," said Jean-Andre Noel, 39, a computer technician. "Those who live in Haiti need everything. We need food, we need drink, we need medicine. We need help."
Were his parishioners being helped? Toussaint was asked. "Not yet," he replied.
The UN World Food Program was "pretty well on target to reach more than 60,000 people today," up from 40,000 the previous day, WFP spokesman David Orr said. But UN officials said they must raise that to two million within a month. The U.S. aid chief, Rajiv Shah, told "Fox News Sunday" he believed the U.S. distributed 130,000 "meals ready to eat" on Saturday, but the need was much larger. "We're really trying to address it," he said.
In a further sign of the delays, the aid group CARE had yet to set a plan for distributing 38 tons of WFP high-energy biscuits in outlying areas of Haiti, CARE spokesman Brian Feagans said Sunday. He did not say why.
The Geneva-based aid group Doctors Without Borders put it bluntly: "There is little sign of significant aid distribution."
The "major difficulty," it said, was the bottleneck at the airport, under U.S. military control. It said a flight carrying its own inflatable hospital was denied landing clearance and was being trucked overland from Santo Domingo, almost 200 miles away in the Dominican Republic, delaying its arrival by 24 hours.
French, Brazilian and other officials had earlier complained about the U.S.-run airport's refusal to allow their supply planes to land.
The U.S. has completely taken over Port-au-Prince airspace and incoming flights have to register with Tyndall Air Force Base in Florida, said Chief Master Sgt. Ty Foster, Air Force spokesman here.
"You won't have the stray cats and dogs allowed to come into the airspace and clog it up," he said.
The on-the-ground U.S. commander in Haiti, Lt. Gen. Ken Keen, acknowledged the bottleneck problem. "We're working aggressively to open up other ways to get in here. The ports are part of that," he said on NBC's "Meet the Press."
The White House said Sunday the U.S. Coast Guard ship Oak had arrived at Port-au-Prince harbour, rendered useless for incoming aid because of quake damage, and use heavy cranes and other equipment to make the port functional.
Other U.S. help was on the way: Some 2,000 Marines should arrive off Haiti on Monday, Keen said, reinforcing 1,000 U.S. troops on the ground.
Meanwhile, Canada announced Sunday it's sending another 1,000 soldiers to to Haiti this week to provide relief and security.
The troops from 3rd Battalion, Royal 22nd Regiment (Vandoos) based at Canadian Forces Base Valcartier in Quebec will be involved in peacekeeping and reconstruction.
In the Port-au-Prince neighbourhood of Delmas, a crowd gathered Sunday around the bodies of two accused looters, who had been beaten to death by angry residents. Onlookers said they were among 4,000 prisoners who escaped when the main prison collapsed in the quake.
Angry survivors loitered amid piles of burning garbage in the Bel-Air slum. "White guys, get the hell out!" they shouted in apparent frustration at the sight of more and more foreigners in their streets who were not delivering help.
They also sounded furious with President Rene Preval, who hasn't been seen at a rescue site or gone on radio to address the nation since the quake struck.
"Preval out! Aristide come back!" some shouted, appealing for a return of the populist Jean-Bertrand Aristide, who was ousted in 2004. From his South African exile, Aristide said last week he wants to return to Haiti, but spoke of no concrete plans to do so.
Work went on, meanwhile, perhaps in its desperate final hours, to find survivors buried in the vast rubble of Port-au-Prince.
At the UN headquarters destroyed in the quake, rescuers lifted a Danish staff member alive from the ruins, just 15 minutes after Secretary-General Moon visited the site, where UN mission chief Hedi Annai and at least 39 other staff members were killed. The rescued man was talking and smiling as he was whisked away for medical treatment. Hundreds of peacekeepers and other UN staff remain missing.
And at a collapsed Caribbean Supermarket where search teams from Florida and New York City worked overnight, a policeman reported that three people had been pulled out alive around 6 a.m.
More than 1,700 rescue workers had saved more than 70 lives since the quake, a UN spokeswoman said in Geneva.
