NY Bomb Probe Focusing on Pakistani Taliban

The Pakistani Taliban's claim of responsibility for the Times Square bombing was greeted with widespread skepticism, but investigators are now focusing on the group in the wake of suspect Faisal Shahzad's arrest. Shahzad has told interrogators that he received training in Waziristan—a militant hotbed in Pakistan's frontier region—and officials say the Taliban is one of only a few groups capable of providing bomb-making training.

Taliban involvement is "a leading line of inquiry," a law enforcement official tells the Washington Post. The Pakistani Taliban has, until now, been seen as a group with little interest in carrying out attacks outside its local area, but security analysts fear it's now ready to go global. The lines between the various Islamic militant groups in Pakistan are becoming blurred and it may take some time to determine which group Shahzad is affiliated with, experts tell AFP.
