At least two people have died and five others are reported missing in massive flooding after a tropical storm triggered heavy rains in central Vietnam.
Typhoon Nari, which has moved over Laos after leaving a trail of destruction in Vietnam, caused dangerous floods in the north-central provinces of Quang Binh and Ha Tinh.
Early Wednesday two men, Mai Phu and Phan Son, both 50, were killed when a wall was blown over by a gust in a village in Quang Binh.
The gust, which lasted 15 minutes, also knocked down many houses in the village and injured 24 people.
Also Wednesday morning two women, Nguyen Thi Luc and Nguyen Thi Bich Thuong, both teachers, were swept away by flash floods while they were on their way to school in Quang Binh's Bo Trach District. They have not been found yet.
Some places in Quang Binh received more than 50 cm of rainfall, which saw water levels in rivers rise to record highs.
Local authorities fear the flooding could reach the historic levels of 2010.
Heavy rains also inundated hundreds of houses and roads in Le Thuy District.
In Ha Tinh Province, heavy rains in the last two days left three missing and more than 1,000 houses submerged under water.
Authorities in Huong Khe District evacuated more than 90 families to safer places.
Floods also disrupted traffic and isolated some mountainous districts.
Typhoon Nari, which slammed into central Vietnam early Tuesday, had claimed four lives, caused injuries to 49 others, and left six missing as of Tuesday evening.
It also damaged thousands of houses, knocked down trees, sank dozens of fishing boats, and destroyed crops and other properties.
The total loss is estimated at VND1.5 trillion (US$71 million), with Da Nang and Quang Ngai saying they are the hardest hit.
