NEW YORK (CNN) -- Police Commissioner Ray Kelly warned Friday of possible copycat attacks in the wake of last week's massacre in Mumbai, India.
"In many ways, the city of Mumbai bears striking similarities to New York," Kelly told reporters. "It is the country's financial capital, a densely populated cultural metropolis and a hub for the media ... all of these features make it a compelling target."
On November 26, a group of armed gunmen conducted a series of coordinated attacks throughout the Indian city, leaving 179 people dead and hundreds more injured.
Kelly's remarks came at a news conference where he and the department's chief intelligence officers issued security recommendations to New York hotels and other "soft targets."
Lt. Mario Rivera, of the department's intelligence division, recommended hotels have an emergency action plan, take protective measures and be vigilant of suspicious behavior.
Kelly said the attack "reminds us that the threat of international Islamic extremism shows no signs of abating."
