Aid agencies have launched a joint emergency appeal to get food, water and shelter to victims of the devastating Philippines typhoon.
The United Nations estimates that $301m (£190m) will be needed in aid.
"We've just launched an action plan focusing on the areas of food, health, sanitation, shelter, debris removal and also protection of the most vulnerable with the government and I very much hope our donors will be generous," humanitarian chief Valerie Amos told reporters in the capital Manila.

"That plan is for $301m."
The Disasters Emergency Committee (DEC), made up of 14 aid charities, said its members were already responding to the crisis but the scale of the destruction meant there was "huge unmet need".
A "huge injection" of funds is needed to get aid through to victims after the typhoon, known locally as Yolanda, made roads impassable and put airports out of action, the DEC said.
Although the official death toll stands at 1,774, around 10,000 people are thought to have been killed in the city of Tacloban alone.
The UN said 673,000 people have lost their homes while a further 11.3 million could be affected after the typhoon, said to be the strongest ever to make landfall, hit the southeast Asian nation.

Sky's chief correspondent Stuart Ramsay is in Hagnaya in Cebu where he said people are begging on the streets because supplies from NGOs have not yet reached them.
He said nearly 100% of the buildings in the town have been damaged.
"There's concern that there is another weather front likely to hit the area with a lot of rain forecast in the next couple of days."
Authorities said they had evacuated 800,000 people ahead of the typhoon, but many evacuation centres proved to be no protection against the wind and rising water.

The Philippine National Red Cross, responsible for warning the region and giving advice, said people were not prepared for a storm surge.
Although weakened, the typhoon, has also killed eight people and devastated farmland since making landfall in southern China.
DEC chief executive Saleh Saeed said: "The destruction in Tacloban city, on the east coast, is said to be reminiscent of the Boxing Day tsunami.
"There is currently no food, water or electricity. We can only imagine how much worse the situation will be for families living in towns and remote villages.
"DEC members are doing all they can to get aid through but they need a huge injection of funds in order to do so.
"The priorities are getting food, water and shelter to people in desperate need."
Sky's Asia correspondent Mark Stone, on the island of Leyte, said up to 20 people had been killed by falling bags of rice in the scramble to get to aid supplies from a warehouse.
Stone said he had travelled to the island with people who did not know if their family members were alive or not: "There's no mobile phone network here, no way of communicating."
The DEC includes the British Red Cross, Christian Aid, Oxfam and Save the Children.

All of its members will support the appeal and 13 of the 14 are responding either directly or through partner organisations.
The UK is deploying a Royal Navy warship, HMS Daring, and donating £10m of humanitarian assistance in aid for the victims, Prime Minister David Cameron said.
The ship carries equipment to make drinking water from seawater.
Britain will also deploy RAF military transport aircraft in aid of recovery efforts, earmarking at least one C-17 cargo plane to move humanitarian aid and large equipment.
And a 12-strong team of British surgeons and paramedics is being sent to help with the aid effort.
Meanwhile, Australia announced assistance of £5.8m and the US government has pledged $20m in immediate aid and has ordered the aircraft carrier USS George Washington to the sail to the Philippines.
Japan said it will fly a relief team over to the ravaged country and Taiwan is sending £125,000 in aid.
The United Nations World Food Programme has also allocated $2m (£1.25m) and Unicef is sending emergency supplies.
