Behind the high concrete walls of El Salvador's notorious mega-prison, more than 250 Venezuelans deported in March from the United States remain locked up as President Donald Trump ramps up his mass deportations.

For nearly 20 years, Antonio Ventura has been handing over $100 a month from the till of his small grocery store in El Salvador's capital to gangsters in extortion payments. It was the only way to avoid death threats at gunpoint, or worse.
