The New York Police Department (NYPD), learning lessons from the 26/11 Mumbai attack, has taken necessary steps to prevent any such type of terror attempt, a top US cop said today.

"As part of our comprehensive response to what happened in Mumbai, we've held tactical drills and tabletop exercises with officers from our Special Operations Division based on that scenario," New York Police Commissioner Raymond Kelly said in his testimony before the Senate Committee on Homeland Security and Governmental Affairs.
