BHUBANESWAR, India (AP) - Bloated animal carcasses floated in the streets of cyclone-ravaged towns in eastern India Tuesday, raising fears that epidemics could add to a death toll already believed to be in the thousands - perhaps tens of thousands. Starving and homeless survivors of the ferocious storm drank filthy floodwater and scrambled for helicopter-dropped food packets. At least 200,000 people were homeless. A senior army officer involved in the rescue operation estimated the death toll at between 10,000 and 20,000. That would make the storm India's worst, topping the 10,000 killed in a 1971 cyclone. Other officials in Orissa state agreed the cyclone could prove the country's deadliest, but the government's official toll remained in the hundreds.
