Brazil bridge collapse kills10 people

The death toll after a bridge collapse in northern Brazil increased to 10 on Friday, authorities said.

The Juscelino Kubitschek de Oliveira bridge, which connects the states of Maranhao and Tocantins, collapsed on Sunday, sending vehicles and their occupants plunging into the water below.

The Brazilian Navy had been conducting rescues in the area, finding an additional body Thursday six kilometers (3.7 miles) from the accident site and a second victim Friday in the Tocantins River.

"As such, there are 10 dead and seven missing victims so far," the Navy said in a statement.

More than 70 rescuers continued the search nearly a week after the collapse, using a hyperbaric chamber to allow divers to search depths of more than 30 meters (100 feet).

On Tuesday, Brazilian authorities had warned the Tocantins River could have been contaminated with sulfuric acid being transported by two trucks that tumbled into the water. A third truck involved in the accident was carrying pesticides.
