At least seven people were killed and 30 others injured in a bus accident Monday in southern Brazil, the highway patrol said.

The bus went off a highway and plunged into a ravine near Pirai do Sul, a city in Parana state.

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 in Curitiba, media reports said. EFE
