Two tourists from the United States were killed Monday in an accident at the Iguazu Falls on northern Argentina's border with Brazil, authorities said.
Laura Matejik Eberts, 28, and Philip Musgrove, 70, were in an inflatable boat that flipped over after hitting rocks near the base of the waterfall, said Jorge Veron, an official in Misiones province. He did not release their hometowns.
Five other people suffered injuries and were treated at a hospital, Veron said. The injured included one American, two Germans, one Colombian and one Argentine.
Veron said authorities were still trying to determine what caused the accident.
(This version CORRECTS dead woman's name to Matejik Eberts instead of Natejik Evert.)
