CALUMPIT, Philippines (AFP) - The Philippines deployed helicopters, inflatable boats and amphibious vehicles Sunday in a desperate bid to evacuate tens of thousands in the aftermath of successive monster storms. But rescuers and officials said it was close to impossible to pluck everyone to safety, with many refusing appeals to abandon their inundated homes despite warnings that flood waters may continue to rise. "We cannot evacuate them all. There are so many of them. That is impossible," said James de Jesus, mayor of Calumpit town where many residents were caught off-guard by the rising water. "We are calling for help from the armed forces to drop food and water to the thousands still on the roofs or second floor of their homes." Typhoon Nalgae blew out of the Philippines Saturday after a six-hour rampage across the country's main island Luzon, bringing fresh troubles for more than a million people still affected by Typhoon Nesat, which struck five days earlier. The two storms were among the most powerful to have struck the country this year, with their massive rain bands covering most of Luzon.
