A United Nations official confirms that the flag of the Holy See will be raised for the first time outside U.N headquarters the morning of Pope Francis' first visit.

It is a turnaround for the Vatican, whose U.N. ambassador has said it had "no intention" of raising the flag before the pope arrives Sept. 25.

The General Assembly last week overwhelmingly approved a Palestinian proposal to raise its flag and that of the Holy See as the U.N.'s two non-member observer states.

The Palestinians have announced a ceremony for their flag-raising Sept. 30 during the annual U.N. gathering of world leaders. But the Holy See flag is set to be raised quietly.

The official spoke on condition of anonymity because they were not authorized to talk publicly about the event.
