LIMA, June 30 (Xinhua) -- Former Peruvian spy chief Vladimiro Montesinos on Monday refused to give further testimony at ex-president Alberto Fujimori's trail on human rights abuses.

    "From this moment on I won't answer any question (from the prosecutor or lawyers)," the former National Intelligence Service head told the court hearing Fujimori's trial.

    While refusing to give out information about the Intelligence Service, Montesinos said neither he or Fujimori were responsible for the death squad attacks that killed 25 civilians in 1991 and 1992.

    He added that he would testify at his own trial, and the court can request his testimony for Fujimori's case. Montesinos is undergoing a separate trial for the alleged killings.

    Monday's trial was the first time Montesinos and Fujimori met face to face after the latter's government collapsed in 2000.

    Montesinos is now serving a 20-year prison term for crimes including corruption and trafficking of arms to Colombian guerillas. He faces a 35-year penalty if found guilty of organizing the death squad that murdered the said civilians.

    Montesinos was Fujimori's main ally in annihilating the guerilla group of Sendero Luminoso and is accused of having led a wide network of corruption among politicians.
