**More than 2,000 US marines are set to join 1,000 US troops on the ground in Haiti, as aid efforts gather pace almost a week after the earthquake.**Their arrival comes amid reports of violence and looting and as UN and US forces pushed back an angry crowd at the airport gates with batons.
UN chief Ban Ki-Moon said he would recommend the UN Security Council boost police and troop numbers by 3,500.
People have been continuing to flee the capital and many are seeking US visas.
The BBC’s Mark Doyle in Port-au-Prince says perhaps 5,000 people have lined up outside the US embassy, desperate to join relatives among the large Haitian-American community in the US.
But UN humanitarian chief John Holmes played down worries over security, saying that despite incidents of violence, the overall situation was calm.
AT THE SCENE
David Loyn, BBC News, Port-au-PrinceThe US military took over the airport within hours of the earthquake and there’s some disquiet at their large presence among aid workers who believe that humanitarian relief should be purely a civilian affair.
But for their part, the civilian aid effort has been very slow to get into gear. The aid system that existed before was fractured like so much else in the disaster and the responses lack co-ordination.
The deputy head of the World Food Programme here, Ben Yatiri, said that within only a few days many more people would receive food than the 100,000 now being fed - but the worsening security means that every truck that goes out needs very careful planning and a military escort, otherwise it would be attacked.
The delay in delivering aid has made the job far harder now.
His message was echoed by the leading US general in Haiti, Lt Gen Ken Keen, who said there was currently less violence in Port-au-Prince - already a troubled city - than there had been before the earthquake.
Earlier, Lt Gen Keen said up to 200,000 people may have died in the disaster.
He said the disaster was of “epic proportions”, but it was “too early to know” the full human cost.
Delivering aid to the centre of the capital is getting much more difficult, as anger fuelled by hunger reaches boiling point, and military escorts are needed for trucks carrying supplies, the BBC’s David Loyn in Port-au-Prince says.
US Navy helicopters have been dropping packages of ready-to-eat meals and water from the air, but they can only feed a few people at a time, our correspondent adds.
Lt Commander Walter Matthews of the US Navy told the BBC he understood the frustration among Haitians but that the aid effort was improving.
Luca Pupulin, of the French charity Acted, told the BBC he had seen many people heading north away from the capital.
He said: "I think on the whole the community is trying to to do its best, but they are getting very frustrated.
“A couple of days ago we went through the main market street and we didn’t stay very long. People were getting aggressive with each other and pillaging.”
Looting has spread to more parts of downtown Port-au-Prince, the Associated Press news agency reports, with hundreds of young men and boys clambering over rubble to break into shops and take whatever they could find.
Airport complaints
Port-au-Prince’s port is badly damaged, and many roads are still blocked by corpses and debris, hampering the delivery of fuel and other supplies except by air.

Several agencies complained at the weekend about not being able to get aid through the heavily congested airport, which is being run by the US military.
But Mr Holmes said that initial issues were being resolved, with the introduction through the WFP of a system to prioritise humanitarian flights.
As hopes of finding survivors fade, Mr Holmes told reporters that there were now 43 search and rescue teams on the ground, with 1,700 people involved.
“More than 70 people have been pulled from the wreckage in the last few days,” he said, saying that the search would carry on until there was no longer hope of finding anyone alive.
The US Agency for International Development (USAID) said on Monday that American teams had pulled 10 people alive from the rubble the day before.
“According to rescue officials, this is the largest number of rescues in a single day in decades of earthquake search and rescue efforts,” it said in a statement.
At least 70,000 people in Haiti have already had burials.
Aid workers are starting to expand their efforts to earthquake-affected areas outside the capital, including Leogane, Gressier, Petit-Goave and the coastal town of Jacmel.
Aid pledges
Speaking on Monday, UN Secretary General Ban Ki-moon said he would recommend that the UN Security Council boost UN troop numbers in Haiti by 2,000 for six months, and UN police numbers by 1,500.
AID PLEDGES TO HAITI
- EU - $604m (420m euros; £371m)
- US - $100m pledged in immediate aid, with promise of more later
- UK - $32m
- Norway - $17.6m
- France - $14.4m
- World Bank - $100m
Mr Ban, who visited Port-au-Prince on Sunday, added: “The heartbreaking things I saw yesterday compel us to act swiftly and generously.”
The UN has launched an appeal for $562m (£346m) intended to help three million people for six months, most of whom are thought to need emergency relief.
Meanwhile in Brussels, European Union nations pledged more than 420m euros ($604m; £320m) from the EU budget to assist Haiti, with about half the sum dedicated to emergency and short-term aid.
At least 200m euros will be dedicated to funding medium- to long-term rebuilding efforts.
The British government has said it will treble its aid to Haiti to £20m ($32m).
