As war with Iraq appears imminent, the Homeland Security Department has raised the national terror alert and announced a series of security measures called "Operation Liberty Shield."
Homeland Security Secretary Tom Ridge told reporters in Washington Tuesday there will be extra security at U.S. borders, ports, airports and railways. He said governors have been asked to deploy the National Guard and other security officers at key sites.
Ridge said security will increase at petroleum, chemical and nuclear facilities. He said steps are also being taken to protect financial networks.
There will be more inspections of imported foods, and state and local health departments are being asked to report any unusual illnesses.
People seeking asylum from Iraq and more than 30 other countries will be held for background checks. Ridge said the U.S. wants to make sure their claims are legit.
