World leaders were quick to offer prayers and praise following the death of Pope John Paul the Second. In Washington, President Bush said the world has lost a champion of freedom, and the Catholic Church has lost its shepherd. U.N. Secretary General Kofi Annan praised Pope John Paul as a tireless advocate of peace and a true pioneer in interfaith dialogue. British Prime Minister Tony Blair called him a religious leader revered by people of all faiths, and said he never wavered in the struggle for what he thought was good and right. In Rome, the Italian government declared three days of mourning beginning Sunday for the Polish-born pontiff, the first non-Italian pope in nearly five centuries.
