The Jews were targeted first (Islamic antisemitism is a basic tenet in Islam). According to radio transmissions picked up by Indian intelligence, the attackers "would be told by their handlers in Pakistan that the lives of Jews were worth 50 times those of non-Jews."
Islamic Jew hatred; it's in the Quran.
In my extensive coverage of the savage Muslim attacks on the West in Mumbai, India, the obsession with targeting the small little Jewish Chabad house from the inception of the planning was shocking. The Jewish Chabad house was part of a larger attack on hotels and public buildings across Mumbai that resulted in the deaths of at least 166 people. But for the Muslim terrorists themselves, Nariman House was different. It was the only Jewish target, and the Muslim terrorists were told by their central command in Pakistan that the lives of Jews were worth 50 times those of non-Jews. The organizers had sought it out with care. Their handlers would emphasize to them the importance of killing Jews.

Interrogation of terrorist leader finds Jewish establishments in Mumbai scoped out by Muslim group for possible terrorist attacks
Amid a terror threat, Jewish establishments in India have been instructed by police to tighten security in and around their businesses.
According to New Delhi Television (NDTV), Bhatkal told investigators that Jewish establishments in Mumbai have been surveyed by Indian Mujahideen members for possible terrorist strikes. The Islamist militant group reportedly was trying to seize Jewish hostages to trade them for terrorists, the Hindustan Times reported.
Indian police called on Jewish establishments to hire security guards, install security cameras and issue ID cards for admittance to the businesses, according to NDTV. They also have been instructed to not allow parking around their buildings.
There reportedly are 12 Jewish establishments in Mumbai, including four in the southern part of the city. One of the buildings, the Nariman Chabad House, was the site of a November 2008 terror attack in which six people were killed.
Following a nationwide alert issued ahead of Rosh Hashanah in early September, security was increased around the 20 Chabad houses in India, the Hindustan Times reported.
