Rescuers struggled through mud and pounding rain Friday to clear mountain roads and retrieve more than 160 dead from dozens of landslides that buried villages and cut off towns in the rain-soaked northern Philippines. The latest calamity brought the death toll to more than 450 from the Philippines' worst flooding in 40 years after back-to-back storms started pounding the country's north Sept. 26. More than 160 people were killed in landslides in Benguet and Mountain Province along the Cordillera mountain range, about 125 miles (200 kilometers) north of Manila, officials in the two provinces said. "We are focused on rescue at this time," he said. "It is raining nonstop in the Cordilleras." About 100 landslides have struck the region since the weekend, said Rex Manuel, another relief official.
