The death toll from the bus accident in the southern Brazilian state of Parana has risen to at least 10, with 26 other people injured, the highway patrol said.
The bus went off a highway Monday after hitting a truck and plunged into a ravine near Pirai do Sul, a city in Parana.
The bus was traveling from Belem, a city in Para state, to Curitiba, the capital of Parana.
The bus was carrying 52 passengers, who rented the vehicle to take them to an information technology conference that starts on Tuesday in Curitiba, media reports said.
