Rights groups expressed worry Tuesday that President Donald Trump's reinstatement of Cuba on a US terror list could halt the release of "political prisoners" that started just last week under a deal with his predecessor Joe Biden.

Cuba has released prominent dissident José Daniel Ferrer from jail, as part of a Cuban government decision to gradually free more than 500 prisoners as part of talks with the Vatican.

Cuba has started releasing some prisoners as part of talks with the Vatican, a day after President Joe Biden's administration announced his intent to lift the U.S. designation of Cuba as a state sponsor of terrorism.
