Last week, on Sep. 11, al Qaeda's al-Zawahri released an audio message calling for attacks on the United States. "To keep up the hemorrhage in America's security and military spending, we need to keep the United States on a constant state of alert about where and when the next strike will blow. Keeping America on its guard only requires from us scattered strikes here and there," al-Zawahri said, according to CBS News.
"America is not a mythic power and the Americans, after all, are humans who can be defeated, felled and punished," al-Zawahri said, according to the Associated Press.
Examiner asked the U.S. Department of Homeland Security if the attack may have been motivated by al Qaeda's message, but has not heard back yet. Its response will be included once it is received.
