The official Agencia Brasil news agency reports that the collapse of a metal structure at an agricultural fair has killed a woman and injured three other people in Brazil. It says 64-year-old Adriana Ribeiro de Jesus died of a chest wound after the metal structure that served as the exit from the food court collapsed late Saturday during a burst of strong winds. The Contemporary Rural Brazil fair opened on Wednesday in Rio de Janeiro and was slated to run through Sunday, but organizers decided to closer the event following the accident after deciding there wouldn't be enough time to check the structural soundness of all the buildings, AP reported.
