Families in Venezuela are searching for relatives they say have become political prisoners after a failed coup attempt to overthrow President Nicolas Maduro.
According to a Washington Post newspaper report, Venezuela's opposition members negotiated a $213m deal with a small Florida security company to invade the country on May 3.
Venezuelan authorities have arrested more than a dozen people, including Americans who work for a firm, they say were part of the plot.
The US government denies any involvement.
