Portuguese Foreign Minister Diogo Freitas do Amaral will elaborate Tuesday to a parliamentary committee on the government's knowledge of reported CIA flights landing on Portugal's airports.

The minister has refused to reveal the findings over the event until his scheduled appearance before the committee.

On earlier occasion, the minister said Portugal was consulting with the United States and European authorities to probe the CIA flights suspected of transporting war-on-terror captives making landings on the Iberian country.

One newspaper reported that suspected CIA aircraft had made 59 landings in Portuguese airports over the past three years.

The Washington Post and Human Rights Watch first reported the secret CIA Flights, transporting terrorist suspects through some European countries as the Netherlands, Spain, Sweden, Denmark, Norway, Iceland, Germany and Ireland.
