"I’m extremely nervous, waiting for that phone to ring, for them to call us and tell me to go get him," says 64-year-old Liset Fonseca from San Jose de las Lajas, in Cuba's Mayabeque Province. Her son, Roberto Perez Fonseca, was imprisoned for protesting against the Cuban government in 2021. Cuba has begun releasing prisoners as part of an agreement with the administration of outgoing US President Joe Biden, who removed Cuba from the list of state sponsors of terrorism. Cuban authorities have not disclosed the names of the prisoners to be released. IMAGES AND SOUNDBITES
