Thousands of people have been evacuated from low-lying areas in the Vietnamese capital, Hanoi, as the Red River surged to its highest level in two decades, flooding the streets.

On Wednesday, floodwaters from the swollen river reached a meter high in parts of the city, forcing some residents to navigate their neighborhoods by boat.

State media reported that power had been cut to some districts for safety, while 10 of Hanoi’s 30 administrative districts were on flood alert.

Vietnam is dealing with the aftermath of Typhoon Yagi, which battered the north and killed at least 179 people.

Yagi, initially categorized as a super typhoon but later downgraded to a tropical depression, has continued to wreak havoc in Vietnam since making landfall on Saturday.

It has been described as Asia’s most powerful typhoon this year.
