(CNN) There is fresh intelligence of a potential Iranian threat against US forces and interests in the Middle East, according to several US defense and administration officials.

"There has been consistent intelligence in the last several weeks," one administration official told CNN.

A second official described it as information that has been gathered throughout November. The information is being gathered by military and intelligence agencies.

The officials would not say in what format the intelligence exists. But in the last several weeks there has been movement of Iranian forces and weapons that the US worries could be put in place for a potential attack, if one is ordered by the Iranian regime, the officials said. It's not clear if a potential threat would come from the central government or Iran's Islamic Revolutionary Guard Corps.

The head of US military operations in the Middle East recently signaled the US expects some kind of Iranian action in response to the US sanctions and pressure campaign that is trying to get the regime to abandon its nuclear program.
