The Wall Street Journal New York offices evacuated on Wednesday after the newspaper reported 13 envelops containing a white powder were received today.

The New York Police and Fire Departments arrived on the scene which is undergoing investigations.

The envelops had stamps from Tennessee and were addressed to senior executives at the Dow Jones and the Wall Street Journal. Three of them were delivered to the executive's offices, one reportedly was opened by an assistant.

Half of our employees have been evacuated and are working from remote locations, said Robert Christie, Vice President of Communications at the Dow Jones in a video posted on the WSJ website.

The Wall Street Journal plans to deliver its publications as usual tomorrow.

Unidentified white powder is commonly related to a toxic and lethal substance called anthrax. In 2001, there were a series of anthrax attacks that targeted news organizations.
