WASHINGTON — Kuwait has released an additional 10 American detainees, bringing to nearly two dozen the total number freed by the country in the past two months, U.S. officials told The Associated Press on Wednesday.

Taken together, Kuwait’s pardons of 23 Americans since March - done as a goodwill gesture by the U.S. ally - amounted to the largest release of U.S. citizens by a single foreign country in years.

The prisoners include military contractors and veterans held on drug charges and other offenses by the small, oil-rich nation. One detainee was said by supporters to have been coerced into signing a false confession and endured physical violence and threats against his wife and daughter.

Ten others were released on March 12, weeks after a visit to Kuwait by Adam Boehler, who is serving as the Trump administration’s envoy for hostage affairs.
