Teams of gunmen stormed luxury hotels, a popular restaurant, hospitals and a crowded train station in coordinated attacks across India’s financial capital Wednesday night, killing at least 101 people and taking Westerners hostage, police said.

Media reports said that gunmen also seized the Mumbai headquarters of the ultra-orthodox Jewish outreach group Chabad Lubavitch and that shots had been heard coming from the building.

Representatives of the New York-based group referred questions to their Web site, which said the Israeli consulate had earlier been in touch with the rabbi who lived in the house, “but the line was cut in middle of the conversation. No further contact has since been established.”

A group of suspected Muslim militants claimed responsibility for the attacks.

The attackers specifically targeted Britons and Americans at the hotels and restaurant, witnesses said.
