TACLOBAN, Philippines (AP) - As many as 10,000 people are believed dead in one Philippine city alone after one of the worst storms ever recorded unleashed ferocious winds and giant waves that washed away homes and schools. Corpses hung from tree branches and were scattered along sidewalks and among flattened buildings, while looters raided grocery stores and gas stations in search of food, fuel and water. Officials projected the death toll could climb even higher when emergency crews reach areas cut off by flooding and landslides. Even in the disaster-prone Philippines, which regularly contends with earthquakes, volcanoes and tropical cyclones, Typhoon Haiyan appears to be the deadliest natural disaster on record. Haiyan hit the eastern seaboard of the Philippine archipelago on Friday and quickly barreled across its central islands before exiting into the South China Sea, packing winds of 235 kilometers per hour (147 miles per hour) that gusted to 275 kph (170 mph), and a storm surge that caused sea waters to rise 6 meters (20 feet). It wasn't until Sunday that the scale of the devastation became clear, with local officials on hardest-hit Leyte Island saying that there may be 10,000 dead in the provincial capital of Tacloban alone. Reports also trickled in from elsewhere on the island, and from neighboring islands, indicating hundreds, if not thousands of more deaths, though it will be days before the full extent of the storm's impact can be assessed. "On the way to the airport we saw many bodies along the street," said Philippine-born Australian Mila Ward, 53, who was waiting at the Tacloban airport to catch a military flight back to Manila, about 580 kilometers (360 miles) to the northwest. They were covered with just anything - tarpaulin, roofing sheets, cardboards. She said she passed "well over 100" dead bodies along the way. Haiyan raced across the eastern and central Philippines, inflicting serious damage to at least six of the archipelago's more than 7,000 islands, with Leyte, neighboring Samar Island, and the northern part of Cebu appearing to take the hardest hits. It weakened as it crossed the South China Sea before approaching northern Vietnam, where it was forecast to hit land either late Sunday night or early Monday morning. On Leyte, regional police chief Elmer Soria said the provincial governor had told him there were about 10,000 deaths there, primarily from drowning and collapsed buildings. Most of the deaths were in Tacloban, a city of about 200,000 that is the biggest on Leyte Island. On Samar, Leo Dacaynos of the provincial disaster office said 300 people were confirmed dead in one town and another 2,000 were missing, while some towns have yet to be reached by rescuers. He pleaded for food and water and said power was out and there was no cellphone signal, making communication possible only by radio. Reports from the other affected islands indicated dozens, perhaps hundreds more deaths. Television footage from Eastern Samar province's Guiuan township - the first area where the typhoon made landfall - showed a trail of devastation. Many houses were flattened and roads were strewn with debris and uprooted trees. The ABS-CBN footage showed several bodies laid out on the street, covered only with blankets. Even me, I have no house, I have no clothes. I don't know how I will restart my life, I am so confused," an unidentified woman said, crying. I don't know what happened to us. We are appealing for help. Whoever has a good heart, I appeal to you - please help Guiuan. A massive relief operation was underway, but the Philippine National Red Cross said its efforts were being hampered by looters, including some who attacked trucks of food and other relief supplies the agency was shipping Sunday from the southern port city of Davao to Tacloban. With other rampant looting being reported, President Benigno Aquino III said Sunday that he was considering declaring a state of emergency or martial law in Tacloban, as city officials have proposed. The national disaster agency can recommend such a measure if the local government is unable to carry out its functions, Aquino said. A state of emergency usually includes curfews, price and food supply controls, military or police checkpoints and increased security patrols. The massive casualties occurred even though the government had evacuated nearly 800,000 people ahead of the typhoon. About 4 million people were affected by the storm, the national disaster agency said. Aquino flew around Leyte by helicopter on Sunday and landed in Tacloban to get a firsthand look at the disaster. He said the government's priority was to restore power and communications in isolated areas and deliver relief and medical assistance to victims. Challenged to respond to a disaster of such magnitude, the Philippine government also accepted help from its U.S. and European allies. In Washington, Defense Secretary Chuck Hagel directed the military's Pacific Command to deploy ships and aircraft to support search-and-rescue operations and airlift emergency supplies. The United Nations office in Geneva said in a statement Sunday that the U.N. and the "humanitarian community have ramped up critical relief operations," but that access remains a challenge because some areas are still cut off. Pope Francis led tens of thousands of people at the Vatican in silent prayer for the victims of the typhoon. The Philippines has the largest number of Catholics in Asia, and Filipinos are one of Rome's biggest immigrant communities. The Philippines is annually buffeted by tropical storms and typhoons, which are called hurricanes and cyclones elsewhere on the planet. The nation is positioned alongside the warm South Pacific where typhoons are spawned. Many rake the islands with fierce winds and powerful waves each year, and the archipelago's exposed eastern seaboard often bears the brunt. Even by the standards of the Philippines, however, Haiyan is a catastrophe of epic proportions and has shocked the impoverished and densely populated nation of 96 million people. Its winds were among the strongest ever recorded, and it appears to have killed many more people than the previous deadliest Philippine storm, Thelma, which killed around 5,100 people in the central Philippines in 1991. The country's deadliest disaster on record was the 1976 magnitude-7.9 earthquake that triggered a tsunami in the Moro Gulf in the southern Philippines, killing 5,791 people. Tacloban's two largest malls and groceries were looted and the gasoline stations destroyed by the typhoon. Police were deployed to guard a fuel depot to prevent the theft of fuel. Two hundred additional police officers came to Tacloban on Sunday from elsewhere in the country to help restore law and order. Tacloban, in the east-central Philippines, is near the Red Beach on Leyte Island where U.S. Gen. Douglas MacArthur waded ashore in 1944 during World War II and fulfilled his famous pledge: "I shall return." It was the first city liberated from the Japanese by U.S. and Filipino forces and served as the Philippines' temporary capital for several months. It is also the hometown of former Filipino first lady Imelda Marcos, whose nephew, Alfred Romualdez, is the city's mayor. In Torotoro's village, bodies could be seen lying along the muddy main road, as residents who had lost their homes huddled with the few possessions they had managed to save. UNICEF estimated that about 1.7 million children are living in areas impacted by the typhoon, according to the agency's representative in the Philippines, Tomoo Hozumi. The devastation is ... I don't have the words for it," Interior Secretary Mar Roxas said. In Vietnam, about 600,000 people living in the central region who had been evacuated returned to their homes Sunday after the weakened storm changed directions and took aim at the country's north. The storm was approaching landfall Sunday night with sustained winds of 133 kph (83 mph). Four people from three central Vietnamese provinces died while trying to reinforce their homes ahead of the storm, the national floods and storms control department said Sunday.
