American Lori Berenson, on parole after serving most of a 20-year prison sentence for aiding leftist rebels in Peru, returned to the Andean nation from the United States after spending the holidays with her family.

A crowd of reporters was waiting for Berenson and her young son when they disembarked Thursday at Lima’s international airport, but she left the terminal without making any statements.

The U.S. citizen was granted parole in 2010 after serving 15 years of a 20-year sentence and was required to stay in Peru for five more years.
