Six American citizens who were imprisoned in Kuwait have been released as part of efforts by the Trump administration to free Americans in overseas countries.

Private consultant Jonathan Franks said that additional Americans he represents are expected to be released by Kuwait later.

Kuwait has released a group of American prisoners, including veterans and military contractors jailed for years on drug-related charges, in a move seen as a gesture of goodwill between two allies, a representative for the detainees told The Associated Press on Wednesday.

The Americans, many of whom are veterans and former military contractors, were convicted on drug charges, a representative for their families told ABC News.
