Why Were Jews Targeted In Mumbai?

Camille Paglia has a post-Mumbai question for the world's Muslim organizations:

The tragic fate of so many innocent victims in Mumbai deserves our pity. But what should live in special infamy was the ruthless execution of the Lubavitcher rabbi, Gavriel Hertzberg, and his lovely wife, Rivka, who was 5 months pregnant. These were two idealistic young people of obvious warmth and humanity, who sought only to serve. The rescue by their Indian nanny of their orphaned 2-year-old son, Moshe, crying and smeared with his parents' blood, is already legendary. Was this zeroing in on the Chabad Jewish Center in Mumbai about Israel, or was it simply a gruesome eruption of the medieval tradition of anti-Semitism? Why have Muslim organizations, very quick to protest insulting cartoons, been mostly silent about the atrocities in Mumbai?
