Sympathizers submitted hundreds of questions to al-Qaida deputy leader  Ayman al-Zawahri's "online interview" before a recent deadline. Among them: Why hasn't al-Qaida attacked the United States again, why isn't it attacking the Israelis, and when will it be more active in Egypt, Saudi Arabia and Syria?

Al-Qaida's media arm, Al-Sahab, announced in December that al-Zawahri would take questions from the public posted on Islamic militant Web sites and would respond "as soon as possible." So far, there have been no answers.
