Operators of the nation's nuclear power plants should remain vigilant about suspicious activity that could signal a potential terrorist attack, the FBI says in its latest terrorism bulletin.

Things to watch out for include people who are seen photographing the plants or aircraft that fly too close to them, says the bulletin circulated to about 18,000 state and local law enforcement agencies last week.

The FBI has no specific intelligence that an attack is planned against any of the nation's 103 nuclear power plants. But an anonymous senior FBI official told The Associated Press that the bulletin is meant to ensure that plant operators and local law enforcement personnel remain alert to the possibility.

The FBI's message followed the release of new Nuclear Regulatory Commission security rules requiring more training for guards, placing limits on how many hours they can work and mandating additional, classified protective measures to defend against sabotage or terrorist attacks.
