The death toll from one of the world's most powerful typhoons surged on Friday, but the aid effort was still so patchy bodies lay uncollected and thousands tried desperately to evacuate stricken communities across the central Philippines. After long delays, hundreds of international aid workers set up makeshift hospitals and trucked in supplies, while helicopters from a U.S. aircraft carrier ferried medicine and water to remote areas leveled by Typhoon Haiyan a week ago. "There's a change in the pace of the response. I can see the international support coming here," said Captain Victoriano Sambale, a Philippine military doctor who since Saturday has treated patients in a room strewn with dirt and debris.
