Threatening messages have been posted on the White House Facebook page amid heightened alerts surrounding a possible 9/11 terror threat.
"We'll come back U.S.A. One day only 11/9/2011," says one message, featuring a photo of Osama bin Laden, using the date/month formula to reference Sept. 11.
"We'll come to u white house sooooooooooon," says another.
"We'll come back 11/9/2011 to kill u all," a third posting reads.
New York City and Washington, D.C., have tightened security after intelligence collected from overseas indicated a possible threat involving car bombs, as well threats to bridges and tunnels. The information indicated that three men would travel from Pakistan to the U.S. to carry out an attack.
