ea and fishermen died in flimsy boats. The 21-year-old grandson of Thai King Bhumibol Adulyadej was killed on a jet-ski.

"We have a long way to go in collecting bodies," said Thailand's Prime Minister Thaksin Shinawatra, who expected the 839 death toll in his country to go much higher.

Sri Lanka was hardest hit by the tsunami -- a wall of water triggered by the world's biggest earthquake in 40 years with a magnitude of 9.0 that erupted off the northern Indonesian coast. Colombo officials said their latest death toll had nearly doubled to 10,029 and 200 foreign tourists were feared dead.

"It smells so bad ... The human bodies are mixed in with dead animals like dogs, fish, cats and goats," said Marine Colonel Buyung Lelana, head of an evacuation team in Indonesia's Aceh province on the island of Sumatra.

Families around the world anxiously sought news of loved ones on Christmas holidays whose dreams of sunshine in the east were turned into scenes of disaster. Calls from worried relatives swamped hotlines set up by ministries and tour firms.

With at least seven Asian nations and one in East Africa counting the terrible human and economic cost of the tragedy on Monday, Western nations pledged aid and geologists asked why early warning systems that could have saved thousands of lives were not in place.

Struggling with destroyed communications, power outages and swamped and debris-strewn roads, emergency workers were shocked by the sheer scale of the catastrophe.

"We are used to dealing with disasters in one country. But I think something like this spread across many countries and islands is unprecedented. We have not had this before," Yvette Stevens, a U.N. emergency relief official, said in Geneva.

Bodies in Trees, Makeshift Morgues

Other areas worst affected by Sunday's tsunami were southern India, where more than 6,600 were listed dead, northern Indonesia with nearly 5,000 drowned and Thailand's devastated southern tourist isles and beaches.

Deaths were also reported in Bangladesh, Malaysia, the Maldives, Myanmar and distant Somalia where 14 people were killed by swollen seas.

The earthquake triggered a tsunami of up to 33 feet high, sometimes traveling as fast as an airliner, flattening houses, hurling fishing boats onto roads, sending cars spinning through swirling waters into hotel lobbies and sucking sunbathers, babies and fishermen out to sea.

Hundreds of thousands were left homeless.

Smaller tremors followed Sunday's earthquake, the world's biggest since 1964 and the fourth-largest since 1900.

Indonesian rescue workers pulled hundreds of bodies from treetops, rivers and wrecked homes in Aceh province Monday, desperate to clean up before disease could spread from rotting bodies polluting water supplies.

Volunteers laid children's bodies in rows under sarongs at makeshift morgues. Others were stacked in white fish crates.

"I am hoping there are still enough coffins available," said Mustofa, mayor of Aceh's Bireuen regency. One senior official said the toll in Aceh province could rise to up to 10,000. Deaths were previously put at 3,000.

In Banda Aceh, capital of Aceh near the quake's epicenter, troops were unloading piles of bodies from military trucks on Monday after the tsunami swept several miles inland.

In the center of the sprawling city, dozens of bodies were scattered on streets, while masses of debris -- a mix of mud, ruined trucks and cars, mangled motorcycles and wood from shattered houses -- had yet to be cleared.

Throughout the region, relatives hunted through piles of dead stacked up in hospital corridors and prayed for the safe return of thousands still missing. Some pinned up photographs to try to track down the missing.

Death Came from the Sea

"Death came from the sea," Satya Kumari, a construction worker living on the outskirts of the former French enclave of Pondicherry, India, told Reuters. "The waves just kept chasing us. It swept away all our huts. What did we do to deserve this?"

Some of the dead were foreign tourists. Among those killed in Sri Lanka were at least nine Japanese who had been watching elephants in a park when the tsunami swept over them.

"The scale of the tragedy is massive. Sri Lanka has never been hit by tidal waves or earthquakes or anything at all in its known history so this is a grave tragedy which we have not been prepared for," President Chandrika Kumaratunga told the BBC.

Hundreds of thousands in Sri Lanka left homeless and fearing another wave sheltered in temples and schools. The southern port of Galle, famed for its historic fort, had been submerged.

Weeping relatives scrambled over hundreds of bodies piled in a hospital in nearby Karapitiya, shirts or handkerchiefs clutched over their noses against the stench of decaying flesh.

"We are struggling to cope. Bodies are still coming in," said Dr H.G. Jayaratne of Karapitiya Teaching Hospital.

Hundreds of corpses lay bloated and disfigured throughout the lobby and corridors of the hospital.

Thailand evacuated injured survivors from its southern beaches Monday. Some hospitals in Phuket began releasing unofficial, hand-written lists of the dead and injured in their care. Many foreigners were labeled "nationality unknown."

On Phuket's Patong beach, hotels and restaurants were wrecked and speed boats were rammed into buildings.

Many foreign tourists, some evacuated in their bathing costumes, were left destitute, all their possessions and passports lost to the waves.

Among the missing in India were 200 Hindu pilgrims who went for a ritual sea bath. Hundreds scattered petals on the water and sacrificed chickens to pray for their loved ones' return.
