The death toll from devastating flash floods and landslides that hit the Brazilian tourist city of Petropolis has risen to at least 104 people and 35 people are missing, officials said Thursday.

Twenty-four people were rescued alive and at least eight victims are children, the State Department of Civil Defense said.

The Petropolis mayor's office declared a state of public disaster and dispatched medical teams to assist victims.

Videos shared on social media showed extensive damage and vehicles floating in the streets.

Petropolis is a popular tourist destination, located in the mountains north of Rio de Janeiro, that was once the summer residence of the Brazilian emperor.
