The top human rights court in Latin America has upheld the conviction of Lori Berenson, a U.S. woman who has been imprisoned in Peru for terrorist collaboration.

President Alejandro Toledo Thursday welcomed the decision of the Inter-American Court of Human Rights.

Berenson had appealed to the court after the Peruvian Supreme Court upheld her conviction.  Her family and lawyers argued that she had not been given a fair trial.

Berenson was arrested in 1995 and accused of involvement in a failed attempt by the rebel Tupac Amaru Revolutionary Movement to seize Peru's Congress.  She has maintained her innocence.
