VATICAN CITY (AP) -- Pope John Paul II, the Polish pontiff who led the Roman Catholic Church for more than a quarter century and became history's most-traveled pope, has died at 84, the Vatican announced in an e-mail Saturday.

As a mark of respect for His Holiness Pope John Paul II, I hereby order, by the authority vested in me by the Constitution and laws of the United States of America, that the flag of the United States shall be flown at half-staff at the White House and on all public buildings and grounds, at all military posts and naval stations, and on all naval vessels of the federal government in the District of Columbia and throughout the United States and its territories and possessions until sunset on the day of his interment.

I also direct that the flag shall be flown at half-staff for the same period at all United States embassies, legations, consular offices, and other facilities abroad, including all military facilities and naval vessels and stations.

IN WITNESS WHEREOF, I have hereunto set my hand this second day of April, in the year of our Lord two thousand five, and of the Independence of the United States of America the two hundred and twenty-ninth.
