At least 10 people have died after floods spurred by Typhoon rains struck central and northern Vietnam, authorities said Saturday.
The southeast Asian country is prone to monsoon storms and floods, which frequently claim hundreds of lives every year.
Typhoon Son Tinh, the third tropical storm to hit Vietnam since the start of the year, made landfall Wednesday night, damaging infrastructure and crops through Thanh Hoa and Nghe An provinces.
Heavy rains have continued in the wake of the typhoon, unleashing floods and landslides across vast areas of the country, including in the capital Hanoi.
According to a latest online report by the disaster office, at least 10 people have been confirmed dead and another 11 are missing in the mountainous northern provinces of Yen Bai and Thanh Hoa.
About 4,000 houses have been damaged and tens of thousands of hectares of crops destroyed, the office said, warning of more heavy rains to come.
State media ran images of floods in remote areas where villagers are using boats to move around. Several communities are still isolated, reports said.
In Hanoi, flood water inundated several streets.
"We had to move all our furniture upstairs because the ground floor was flooded," Hanoi resident Tran Anh Huong told AFP.
"We were all trapped in the house."
Vietnam's rainy season is between June and November, bringing about serious human and material damage.
Last year, 389 lives were claimed by natural disasters, with material damages reportedly reaching $2.6 billion, the government said.
