RIO DE JANEIRO (AP) — Massive floods in Brazil’s southern Rio Grande do Sul state killed at least 60 people and another 101 were reported missing, according to Sunday’s toll from local authorities.

At least 155 people were injured, while damage from the rains forced more than 80,000 people from their homes. Approximately 15,000 took refuge in schools, gymnasiums and other temporary shelters.

The floods left a wake of devastation, including landslides, washed-out roads and collapsed bridges across the state. Operators reported electricity and communications cuts. More than 800,000 people are without a water supply, according to the civil defense agency, which cited figures from water company Corsan.

On Saturday evening, residents in the town of Canoas stood up to their shoulders in muddy water and formed a human chain to pull boats carrying people to safety, according to video footage shared by local UOL news network.
