U.S. diplomatic posts are now closed in the Muslim world because of potential terror threats. Why today? It’s the 27th day of Ramadan, when the first verses of the Koran were revealed to the Prophet Mohammed, says Peter Bergen, a journalist who has written extensively on al-Qaida and interviewed Osama bin Laden in 1997.
It’s considered by Muslims to be “the night of power,” and by “would-be martyrs as a particularly auspicious day to die,” Bergen writes on cnn.com.
In 2000, when it fell on January 3, al-Qaida tried but failed to attack the USS The Sullivans off Yemen. Ten months later, they hit the USS Cole, killing 17 sailors and injuring 39.
