The death toll from landslides and flash floods in the eastern Philippines jumped to nearly 340 with 150 others missing Tuesday, most of them from a region still reeling from last week's deadly typhoon. Social Welfare Secretary Corazon Soliman, who returned to Manila late Tuesday afternoon from an aerial survey of the area, said 306 people were killed and 150 missing in Quezon province, about 70 kilometers (40 miles) east of Manila. The Office of Civil Defense reported 19 were killed in Aurora province, eight in Rizal province, and one each in the Manila suburb of Marikina and Camarines Norte province. Other officials reported three died in Bulacan province north of Manila. Soliman told ABS-CBN television that bad weather and roads blocked by landslides and submerged in flood waters prevented authorities from delivering relief supplies and rescuing people on rooftops.
