A Cuban-American professor accused of spying for Havana has pleaded guilty to lesser conspiracy charges in a U.S. court.
Carlos Alvarez agreed Tuesday to the charge of becoming an unregistered foreign agent. A judge in the southeastern state of Florida set a sentencing hearing for February on the charge, which carries a maximum jail term of five years.
Officials said the man's wife, Elsa, pleaded guilty to charges of failing to notify U.S. authorities about her husband's activities. She faces up to three years in prison.
Prosecutors had accused Carlos Alvarez of spying on Cuban exile groups and anti-Castro figures in Florida for nearly 30 years.
Defense lawyers for Alvarez said he began the activities in an effort to increase dialogue between the governments.
