A man holds a candle and a sign asking for the release of his brother, during a vigil called by the opposition demanding freedom for political prisoners arrested during protest following the contested re-election of Venezuelan President Nicolas Maduro in Caracas, August 8, 2024. Venezuela's opposition warned of a potential mass exodus of migrants if President Nicolas Maduro remains in power following his contested reelection, with the US calling on the strongman not to arrest protest leaders.
