A powerful ocean storm caused deadly floods and landslides in the northern part of Vietnam over the weekend. Typhoon Yagi is the strongest such storm to hit the country in years. In Phu Tho province, a bridge over the Red River collapsed Monday. Reports said 10 cars and trucks and two motorbikes fell into the river. Rescuers saved three people from the river. Thirteen others are missing. In Cao Ban province, a landslide pushed a bus carrying 20 people into a flooded stream. In the northern town of Sa Pa, a popular area for foreign visitors, a landslide killed six people on Sunday. The storm is responsible for at least 59 deaths in Vietnam, officials said. Northern Vietnam is a center for manufacturing. Many foreign companies have operations there, and it is a base for export activity.
