The death toll from torrential rains that triggered floods and landslides in northeastern Brazil has risen to 106, and 10 people were still unaccounted for, the government said on Tuesday.

The heavy rains tore through urban towns in the northeastern part of the country for a sixth consecutive day.

The National Civil Defense said on Twitter that an alert was in place for the "very high" possibility of more flooding in Pernambuco, including its capital, Recife.

Brazilian President Jair Bolsonaro visited the state on Tuesday and flew over the affected areas. He promised to send help and resources to families who had been impacted.
