Boston Marathon bombing suspects Tamerlan and Dzhokhar Tsarnaev planned to travel to New York City and detonate explosives in Times Square, FBI officials told New York Mayor Michael Bloomberg (I) and other city officials.

“Last night, we were informed by the FBI that the surviving attacker revealed that New York City was next on their list of targets,” Bloomberg said on Thursday. “He told the FBI apparently that he and his brother had intended to drive to New York and detonate additional explosives in Times Square. They had built these additional explosives and we know they had the capacity to carry out the attacks.”
