The Cuban government has released 2,010 prisoners, marking one of the largest prison releases in years. The majority of these prisoners were not serving time for political charges, but many were protesters. The release comes amid high tensions between the US and Cuba, with the Trump administration imposing an oil blockade. Human rights groups are demanding clarity and the release of protesters. It is unclear whether any of the prisoners released are among the 1,214 people activist groups say are imprisoned for political reasons in Cuba. The government denies holding political prisoners. The lack of information over the releases has fueled frustration among human rights and opposition groups, who believe the release falls short of real change.
