Wikileaks, an activist group, Wednesday began posting 573,000 intercepted pager messages supposedly sent by the frenzied New Yorkers, and federal and New York’s local officials, during the 9/11 attacks, which killed 3,000 people in the US in 2001.

The Web broadcast of the messages simultaneously on Wikileaks and social networking site Twitter, from Wednesday till Thursday morning, coincides with the actual time duration of the actual messages sent on September 11, 2001 – while the first message was sent at 0300 local time (0800 GMT), five hours before the first attack on the World Trade Center; the last message was sent 24 hours later.

Though most of the message related to the deadly plane attacks, there are also messages about routine matters. While some messages reveal the people’s anxiety over the safety of their loved ones; there were also some government messages, and computer server errors.

Though Wikileaks has stated that it would not reveal the names of the senders of these wide-ranging messages; Internet analysts are of the opinion that the messages are authentic. 

According to Wikileaks spokesman Daniel Schmitt, the posted messages were received by the site several weeks back, and have been sent by an anonymous sender. 

Noting the messages would help provide a complete picture the happenings on 9/11, Schmitt told Associated Press: “From the context information that the source provided we have strong reasons to believe that this is valid data.”
