"Ten thousand, I think, is too much," Aquino said in an interview. "There was emotional drama involved with that particular estimate.”

Aquino said the government was still gathering information from various storm-struck areas and the death toll may rise.

"We're hoping to be able to contact something like 29 municipalities left wherein we still have to establish their numbers, especially for the missing, but so far 2,000, about 2,500, is the number we are working on as far as deaths are concerned," he said.

The official death toll stood at 1,774 on Tuesday.

Philippine officials have been overwhelmed by Haiyan, one of the strongest typhoons on record, which tore through the central Philippines on Friday and flattened Tacloban, coastal capital of Leyte province where officials had feared 10,000 people died, many drowning in a tsunami-like wall of seawater.

Aquino revealed the lower estimated toll after the nuclear-powered aircraft carrier USS George Washington set sail for the Philippines carrying about 5,000 sailors and more than 80 aircraft to accelerate relief efforts. It was joined by four other US Navy ships and should arrive in two to three days, the Pentagon said.

"The weather is pretty bad out there, so we are limited by seas and wind," captain Thomas Disy, commander of the USS Antietam, a missile cruiser that is part of the carrier group, said in Hong Kong. "But we are going to be going as fast as we possibly can."

Relief supplies poured into Tacloban along roads flanked with corpses and canyons of debris as the rain fell again. Rescue workers scrambled to reach other towns and villages still cut off, which could reveal the full extent of the casualties and devastation.

"There are hundreds of other towns and villages stretched over thousands of kilometres that were in the path of the typhoon and with which all communication has been cut," said Natasha Reyes, emergency coordinator in the Philippines at Médecins Sans Frontières.

"No one knows what the situation is like in these more rural and remote places, and it's going to be some time before we have a full picture."

She described the devastation as unprecedented for the Philippines, a disaster-prone archipelago of more than 7,000 islands that sees about 20 typhoons a year, likening the storm to "a massive earthquake followed by huge floods."

About 660,000 people have been displaced and many have no access to food, water or medicine, the United Nations said.

Britain is also sending a navy warship with equipment to make drinking water from seawater and a military transport aircraft. The HMS Daring left Singapore and expects to arrive in two or three days.

World Bank President Jim Yong Kim said the development lender was considering boosting its conditional cash transfer program for the Philippines in the wake of the storm.

Relief efforts picking up

Finance Secretary Cesar Purisima said the economic damage in the coconut- and rice-growing region would likely shave 1 percentage point off of economic growth in 2014.

"Fixation over numbers at this stage is not going to be useful," Purisima, the top Finance Ministry official, told reporters. "I was overwhelmed by the pictures, not the numbers."

The overall financial cost of the destruction was harder to assess. Initial estimates varied widely, with a report from German-based CEDIM Forensic Disaster Analysis putting the total at USD 8 billion to USD 19 billion.

International relief efforts have begun to gather pace, with dozens of countries and organizations pledging tens of millions of dollars in aid. UN aid chief Valerie Amos, who has travelled to the Philippines, released USD 25 million for aid relief on Monday from the UN Central Emergency Response Fund.

Rescuers have yet to reach remote parts of the coast, such as Guiuan, a city of 40,000 people that was largely destroyed.

"We don't need aerial surveys. It won't help the people of Guiuan," one resident posted on the Armed Forces Facebook page. "You've already done an aerial survey and you've seen the extent of the damage, seen the devastation that Yolanda brought. The people are desperate, hungry and feeling dejected. We are crying for help!!!"

The typhoon also levelled Basey, a seaside town in Samar province about 10 km (6 miles) across a bay from Tacloban. About 2,000 people were missing in Basey, its governor said.
