Washington (CNN) -- U.S. officials said Thursday evening they have "specific, credible but unconfirmed" information about a threat against the United States coinciding with the 10th anniversary of the September 11 terrorist attacks.

"We have received credible information very recently about a possible plot directed at the homeland that seems to be focused on New York and Washington, D.C.," a senior administration official told CNN Pentagon Correspondent Barbara Starr.

The plot is believed to involve three individuals who have possibly entered the United States, at least one believed to be a U.S. citizen, the official said.

Shepard Smith referenced it.
