The Juscelino Kubitschek de Oliveira bridge connecting two northern Brazilian states collapsed, killing at least two people and leaving a dozen others missing, according to AP News.
A sulfuric acid spill is complicating the rescue operation. Police operating on the border of the northern states of Maranhão and Tocantins said eight vehicles were missing: four trucks, two cars and two motorbikes.
Magnum Coelho, a colonel in the local fire service, told reporters it was dangerous to send divers for rescue operations, as the Tocantins River could have been contaminated with sulphuric acid from one of the missing trucks that fell off the bridge.
The bridge collapse was one of several tragedies that struck Brazil over the weekend. On Saturday, a collision between a passenger bus and a truck on a highway in Minas Gerais killed dozens of people. On Sunday night, authorities confirmed the death toll had risen to 41.
The Minas Gerais State Fire Department reported that several people were taken to hospitals in the area of the city of Teófilo Otoni. The bus was reportedly travelling from São Paulo and was carrying 45 passengers.
Also on Sunday, at least 10 people were killed after a small plane crashed in Gramado, a southern town popular with tourists. The plane was piloted by Luiz Claudio Galeazzi, a Brazilian businessman who was travelling with his family to São Paulo State.
