Venezuelan opposition leader and Nobel Peace Prize winner María Corina Machado returns home after 10 months abroad, in a move that could challenge the country's interim leadership.
Brazil's 80-year-old left-wing President Lula defeats Flávio Bolsonaro in a bitterly contested runoff and a stunning comeback.
Brazil's left-wing President has been elected for a fourth term after narrowly beating right-wing Flávio Bolsonaro in a knife-edge vote.
The incumbent president has pulled off a surprise win, but he will face a hostile Congress and a polarised country.
Machado had left the country just a month before the US government seized Venezuelan President Nicolás Maduro.
Machado announced her arrival on social media, writing "I am here. With you."
