PORT-AU-PRINCE, Haiti: Relief workers say pockets of violence in Haiti's devastated capital are hindering a slow increase in much-needed aid delivery, and some residents have banded together to protect the few possessions they have left.

As thousands of others head to the countryside, people in one hillside Port-au-Prince district blocked off access to their street with cars and asked local young men to patrol for looters.

"We never count on the government here," said Tatony Vieux, 29. "Never."

But the scope of catastrophe had widened dramatically. The latest casualty report, from the European Commission citing Haitian government figures, doubled previous estimates of the dead to approximately 200,000, with some 70,000 bodies recovered and trucked off to mass graves.

The port remains blocked. Distribution of food, water and supplies from the city's lone airport to the needy are increasing but still remained a work in progress, frustrating many survivors who sleep in the streets and outdoor camps of tens of thousands. European Commission analysts estimate 250,000 were injured and 1.5 million were made homeless.

"I simply don't understand what is taking the foreigners so long," said Raymond Saintfort, a pharmacist who brought two suitcases of aspirin and antiseptics to the ruins of a nursing home where dozens of residents suffered.

The UN humanitarian chief, John Holmes, said not all 15 planned UN food distribution points were up and running yet. The UN World Food Program said it expected to boost operations to feeding 97,000 on Monday. But it needs 100 million prepared meals over the next 30 days, and it appealed for more government donations.

In one step to reassure frustrated aid groups, the US military agreed to give aid deliveries priority over military flights at the now-US-run airport here, according to the WFP. The Americans' handling of civilian flights had angered some humanitarian officials.

At the airport, US Navy Cmdr. Chris Lounderman said about 100 flights a day were now landing.

Still, the US military resorted to an air drop from C-17 transport planes Monday, parachuting pallets of supplies to a secured area outside the city rather than landing and unloading at the airport.

Meanwhile, rescuers continued finding survivors.

International rescue teams working together pulled two Haitian women from a collapsed university building, using machinery commonly nicknamed "jaws of life" to cut away debris and allow rescuers to pull them out on stretchers. A sister of one of the survivors shouted praises to God when the women emerged.

In the city's Bourdon area, a large team of French, Dominican and Panamanian rescuers using high-tech detection equipment said they heard heartbeats underneath the rubble of a bank building and worked into the night to try and rescue a survivor. The husband of a missing woman watched from a crowd of onlookers,

"I'm going to be here until I find my wife, I'll keep it up until I find her, dead or alive," said Witchar Longfosse.
