Polls close in Brazil as Lula and Flávio Bolsonaro remain neck and neck

Polls have closed in Brazil's general election, after voters queued in long lines for a tight first round of the presidential race.
After casting his ballot, 80-year-old left-wing President Luiz Inácio Lula da Silva warned that the choice was between democracy and "barbarism".
His challenger, right-winger Flávio Bolsonaro, 45, said he wanted to "free the Brazilian people".
