A tornado was seen forming near a busy highway in Vietnam.

Dramatic footage shows a funnel cloud building in the sky, gradually evolving into a large twister in Hanoi on August 26, with the Nhat Tan Bridge visible in the foreground amid heavy rain.

There were no immediate reports of injuries following the weather event at 1:35 pm.

Vietnam has recently been battered by Typhoon Kajiki, which made landfall on Monday, leaving at least seven people dead, one missing, and 34 others injured. Officials said more than 7,000 homes were damaged during the storm.

In Thailand, a landslide triggered by the storm killed at least two people.

The weather system has since crossed into Laos and weakened into a tropical depression, with wind speeds of up to 55mph.

Authorities warned that the freak weather is also expected to affect northern Thailand, eastern Cambodia, and central Myanmar.
