The Coding of an Attack
Prior to previous and significant terrorist attacks, a "coded message" was posted on an Arabic forum. This message cryptically referred to a series of numbers and in particular, "Four-four" or "4 4." The following is an incomplete listing of forum messages, supplemented by information concerning the consequential or "planned" attacks believed to be referenced by the "4 4" message. The resurrection of the "4 4" message and references thereto are being noted in Islamic Jihad messages. The following is a compilation of messages, with notations made by analysts. The information is being analyzed for consideration in the possible attacks in the US during Ramadan 2003. Analysts note: although there are three locations of interest- New York, Washington, DC and Los Angeles, CA, analysts are considering the following scenario:
An initial "blast from the sea" may strike the east coast of New York, possibly in a harbor and/or near the New York-New Jersey border. The nature of this blast will most likely be radiological in nature. Following this blast, it is expected that some type of communication by terrorists will be attempted with US leaders. Failing that, a rapid succession of blasts could occur at the "remaining" locations. For those readers keeping count, this would account for only three (3) attacked cities or sites. Analysts are split between a "fourth" blast in tandem with the third (i.e. Los Angeles AND the Silicone Valley area of California) ---or a "fourth blast elsewhere in the US, possibly at a United States landmark. Considering the latter, analysts have noted an obvious interest with Yellowstone National Park, which is the site of active earth-seismic activity.
