Philippine police say a truck carrying more than 60 people from a wedding has plunged into a ravine in the country's mountainous north, killing four passengers and injuring the rest. Police Superintendent Davy Vicente Limmong says the truck was carrying villagers back home from the celebration in the mountain town of Mayoyao in Ifugao province when a part of the narrow road gave in Saturday, causing the vehicle to plummet into a 100-meter (328-foot) ravine. Limmong said Sunday that 31 of the more than 50 injured passengers had serious injuries, according to a report of the Associated Press.
