Paya, 60, and fellow opposition activist Harold Cepero Escalante died Sunday after their car crashed near La Gavina, Cuba. Spanish politician Angel Carromero, the driver, and Swedish politician Aron Modig survived the crash and were discharged from a hospital Monday.
Cuban government officials said Sunday said witnesses said the car veered out of control on its own and crashed into a tree. Police were investigating the accident, a government statement said.
