Cuba will release 51 prisoners in the coming days as a demonstration of "goodwill" following talks with the Vatican, Havana's government has said.
It did not specify whether they included political prisoners, but it said they had all "served a significant portion of their sentences and have maintained good conduct while in prison".
The release comes as Cuban President Miguel Díaz-Canel said that US and Cuban officials were holding talks to find solutions to the two countries' differences. He said no fuel had entered Cuba in three months.
US President Donald Trump said on Monday that Cuba was in "deep trouble" as he threatened a "friendly takeover" of the Caribbean country.
Cuba is experiencing several blackouts as the island struggles with fuel shortages, which have been made worse by pressure from the US.
