WASHINGTON (AP) -- A U.S. Coast Guard ship has arrived in the harbor of Haiti's capital.
The harbor there hasn't been able to handle any incoming relief because it was damaged in Tuesday's earthquake.
Crew members will be using heavy cranes and other equipment to make the port functional.
Also coming from the U.S: about 2,000 Marines are expected in Haiti tomorrow, reinforcing 1,000 American troops who are already on the ground.
Lt. Gen. Ken Keen is the U.S. commander on the ground in Haiti. He says a weakened police force there is causing even the U.N. peacekeeping contingent in Haiti to be overwhelmed as violence increases.
Flare-ups of violence are increasing as a growing number of looters roam the streets of Port-au-Prince.
Many struggling Haitians are angry and frustrated that it's taking so long to get help
At the Vieux Marche, or Old Market, police tried to disperse hundreds of stone-throwing looters today by driving trucks through the crowds. Hundreds scrambled over partly destroyed shops grabbing anything they could.
Elsewhere downtown, gunfire rang out and bands of machete-wielding young men roamed the streets, their faces hidden by bandanas.
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.
WASHINGTON, D.C. (WKOW) -- President Barack Obama is promising U.S. support for Haitian relief would continue long after the scenes of death and destruction fade from the headlines.
Obama says America stands "united with the people of Haiti."
Saturday, Secretary State Hillary Rodham Clinton has arrived in Port-au-Prince where she's to meet with President Rene Preval and get an update on relief efforts. She's accompanied by Rajiv Shah, administrator of the U.S. Agency for International Development, who is acting as the top U.S. relief coordinator.
In Washington, Obama and former presidents George W. Bush and Bill Clinton met in the Oval Office for about half an hour today to discuss the assignment he gave them: to lead private fundraising efforts for Haitian relief, including immediate needs and the long-term rebuilding effort.
Vice President Joe Biden and Homeland Security Secretary Janet Napolitano are in Miami to meet with Haitian-American leaders.
PORT-AU-PRINCE, Haiti (AP) -- Rescue workers are still searching for survivors in damaged and destroyed buildings in Haiti.
They've been able to free people who were trapped in the rubble for days -- including five Americans and two others from the collapsed Montana Hotel. Four of the Americans, rescued yesterday, are in good shape. The fifth, who was found today, was flown out of Haiti. There's no word on the condition of that person.
It's not clear how many others may still be inside the ruins of the hotel, alive or dead.
Experts have said people trapped by Tuesday's quake would not be expected to survive after going without water for three or four days.
PORT-AU-PRINCE, Haiti (AP) -- Aid workers are focusing on the overwhelming challenge of getting food and water to millions of earthquake survivors in Haiti. Meanwhile, government workers are burying thousands of bodies in mass graves.
U.N. peacekeepers say people are growing increasingly desperate and impatient for help. The Brazilian military is warning aid convoys to add security to guard against looting. There has been some looting at the U.N. World Food Program warehouses and at grocery stores.
Hundreds of bodies are stacked outside the city morgue. Haitian President Rene Preval says government crews buried 7,000 bodies in mass graves in one day.
The Red Cross estimates up to 50,000 people were killed in Tuesday's massive earthquake.
PORT-AU-PRINCE, Haiti (AP) -- The U.N. says peacekeepers are maintaining security in earthquake-damaged Haiti, despite challenges that include 4,000 escaped inmates roaming the streets of Port-au-Prince.
Spokeswoman Elisabeth Byrs says the situation is tense, but the peacekeepers are coping with that -- and with the hungry, thirsty people who rush at supply trucks or a collapsed supermarket.
She says there's no need for additional search teams or field hospitals. Seventeen teams are on the ground and six more are on the way. Byrs says any more teams "could compromise the work" of those searching the rubble amid continuing aftershocks. She says the priority for the moment is for medical teams.
The World Health Organization says the scale of the disaster "has overwhelmed all capacities," and more body bags are urgently needed to handle the estimated 50,000 people killed.
PORT-AU-PRINCE, Haiti (AP) -- U.S. military air traffic controllers are scrambling to keep earthquake aid flowing into Haiti's main entry point, its airport.
They're trying to do this without the use of an airport control tower or radar, and amid struggles over fuel, tarmac space and even staircases to access the planes.
The space crunch left some two dozen planes circling for more than two hours yesterday. Many of them had to be diverted to Santo Domingo or Florida.
Thursday's arrivals were dominated by rescue crews leading search dogs and military operations toting supplies and communications equipment.
Doctors Without Borders was able to bring in medical supplies and body bags, but other groups had no luck. The Christian relief organization Samaritan's Purse had three charter planes turned back.
U.S. federal officials had halted nonmilitary flights for eight hours yesterday at the request of the Haitian government. That order has been lifted.
PORT-AU-PRINCE, Haiti (AP) -- A U.N. official has been detailing the lawless and chaotic situation in Haiti's capital.
He says the global aid effort is just getting started, but many people have lost everything and are "slowly getting more angry and impatient."
The U.N. peacekeeping mission spokesman says one problem is that the Haitian national police have "simply vanished." He says that's leaving it up to U.N. forces to keep law and order in Haiti's devastated capital.
That's even as rescue efforts continue at the collapsed U.N. headquarters in Port-au-Prince. About 100 people are believed buried in the rubble.
Spokesman David Wimhurst also described having to grab on to furniture as Tuesday's quake "violently" shook the U.N. offices. He says he and more than a dozen other people managed to escape the wrecked building through his third-story window on a "rather rickety ladder."
PORT-AU-PRINCE, Haiti (AP) -- Dozens of aid flights have arrived in Haiti, but the small damaged airport, poor roads and a damaged port are slowing the delivery of aid.
The airport is short on jet fuel and ramp space. The control tower was destroyed by Tuesday's killer quake. Flight operations have been taken over by the U.S. military.
The international Red Cross estimates 45,000 to 50,000 people have been killed. Hard-pressed recovery teams have resorted to using bulldozers to transport loads of dead.
Uncounted bodies litter the streets in the 80-degree heat. And dust-caked arms of lifeless victims reach from ruins. Brazilian U.N. peacekeepers are organizing mass burials.
The injured, meanwhile, are waiting for treatment in makeshift holding areas outside the General Hospital where the stench from piles of dead is inescapable.
Frustration is beginning to mount among some desperate for water and food. Some are scavenging flattened shops looking for provisions.
PORT-AU-PRINCE, Haiti (AP) -- More than two days after the Haiti earthquake, the bodies of some of the dead are still in the streets of the capital, often covered by a white cloth.
In other cases, people are dragging dust-covered bodies along the road toward the morgue. there, people have been hunting for relatives among the victims, just a few feet from where badly injured victims have waited for treatment by a doctor from the neighboring hospital.
And some victims are being buried by family members along the road, or in nearby hills.
It's been mostly calm in the Haitian capital, which is often a chaotic place.
There's been widespread looting of collapsed buildings, but an American Red Cross official points out that there's no other way to get provisions. And he says undamaged shops have mostly been left alone.
Still, some aid groups are expressing concern about security. An Oxfam spokesman says it's "dangerous at night" in the capital, with widespread looting.
