The White House says President Bush and first lady Laura Bush have joined millions of people around the world in praying for the pope. White House spokesman Scott McClellan says the outpouring of love and concern for the pope from so many -- including millions of Americans -- is a testimony to what he called the pontiff's greatness. People around the world, including in the pope's native Poland, are pouring into churches and holding special services for him. Across heavily Catholic Latin America, people prayed and wept. In Italy, political parties canceled final campaign rallies ahead of regional elections Sunday. Churches in New York, Paris, Nairobi, Moscow, Bethlehem and Jerusalem's Old City, as well as in other parts of the world, have held special prayers for the pontiff. In the Middle East, Muslims joined Christians in expressing concern for the pope, who was known for his support of inter-faith dialogue.
