I have nothing to add to the comments that have already been made on other blogs and news sources, however I wanted to repost a few of the more powerful images.
The Muqata has a copy of the Tfilla that was hanging above 11 Year Old Yoav Fogel's bed, we could should all internalize the message of this Tfilla:
May it be Your will, the Lord my G-d and the G-d of my fathers, that I should merit to love every individual in Israel as if they were my soul, and with my might, and to properly observe the mitzva (commandment) of "Love your Neighbor as Yourself."
And may it be Your will, the Lord my G-d and the G-d of my fathers, that You place in the hearts of my friends, love for me, and that I will be accepted by all, that I should be loved and caring, and find favor in the eyes of all.
As a face is reflected in water, so should the hearts of man be to each other.
And all for the sake of heaven, to observe Your will.
