Only CNN and Obama officials know the secret of the message that closed U.S. embassies Sunday. An intercepted message among senior al Qaeda operatives in the last several days raised alarm bells that led to the closing of embassies and consulates Sunday across the Middle East and North Africa, CNN has learned.
CNN has agreed to a request from an Obama administration official not to publish or broadcast additional details because of the sensitivity of the information. Several U.S. officials also emphasized they have been watching growing threats emerging from Yemen for weeks.
