KARACHI, Pakistan — It's been a rough few days to be Pakistani, at least when it comes to the U.S. struggle against terrorism. Senior White House officials said that last week's Times Square bomb plot was the work of the Pakistani Taliban and not just Faisal Shahzad, the Pakistan native now held in U.S. custody. (On Tuesday, Pakistani security officials denied that link).

BOSTON — The American reaction to Faisal Shahzad’s failed attempt at a car bombing in Times Square was: Pakistan again? Why do so many of terrorism’s hydra-heads originate in Pakistan? Pakistan answered that Shahzad had, after all, spent decades in America and had become an American citizen. So was he radicalized solely in Waziristan’s training camps? Or were the seeds of his radicalization planted here in the United States?

KARACHI, Pakistan — Security officials moved swiftly here to round up as many as eight associates of Faisal Shahzad, the American citizen of Pakistani origin who faces terrorism charges after admitting his role in a failed car-bomb attack Saturday night in Times Square. In a series of raids that stretched into the pre-dawn hours of Wednesday in this southern port city, friends and several family relatives were picked up for questioning, Pakistani authorities told the national media here.
