The Olympic flame, burning inside four golden lamps, arrived in Brasilia aboard a LATAM Airlines jetliner that was escorted inside Brazil's airspace by two Brazilian Air Force F-5 fighters.
The torch left the presidential palace carried by Fabiana Claudino, who led Brazil's female volleyball team to a gold medal in the 2012 Games.
Claudino was chosen as the first torch bearer by Rousseff in honor of the women's volleyball team who are seeking to win the Olympics for a third consecutive time in Rio 2016.
Hundreds of cheering Brazilian lined the streets at the start of the relay and an Air Force aerobatics team swooped over central Brasilia.
