A bridge collapsed and a bus was swept away by flooding in Vietnam on Monday, raising the death toll in the Southeast Asian country to at least 64 from a typhoon and subsequent heavy rains that also damaged factories in export-focused northern industrial hubs, state media reported.

Nine people died on Saturday after Typhoon Yagi made landfall in Vietnam before weakening into a tropical depression. The rest died in the floods and landslides that followed on Sunday and Monday, state media VN Express reported.

The water levels of several rivers in northern Vietnam were dangerously high.

A bus carrying 20 people was swept into a flooded stream by a landslide in mountainous Cao Bang province on Monday morning. State media said four bodies were recovered from the bus and one person was rescued alive. The others were still missing.
