One person was killed and three were injured Wednesday when a helicopter crashed into the sea just off an upmarket Rio de Janeiro beach, the fire department said. A rescue team including a fire department helicopter, divers and jet skis pulled the fatality and three survivors from the wreckage and brought them to the beach, just in front of a Sheraton hotel in one of Rio's poshest neighbourhoods. "The accident left three injured and one dead," the fire department said in a statement. There was no immediate information on the cause of the crash or whom the helicopter was carrying.
