The third typhoon to hit the Philippines in five weeks slammed into the main island of Luzon on Saturday, uprooting trees and toppling power lines, but there were no immediate reports of widespread damage. Authorities cancelled about 180 flights from Manila while some ferry and bus services remained grounded, leaving thousands stranged and stopping people from returning to their home provinces for the All Saints' Day weekend. Two typhoons killed more than 900 people in recent weeks, with parts of the capital, Manila, still under water.
