These are my pictures from 2012 but it is the same ritual every year at the Chapel of the Ascension on the Mount of Olives.
Click a few times on the photos to enjoy the details.

UPDATE: See a little video of this year's celebration: http://www.terrasanctablog.org/2014/06/03/ecumenical-ascension-in-jerusalem/
