The U.S. Transportation Security Administration says starting this week, it is deploying teams of federal air marshals and uniformed law enforcement officers at bus and train stations across the country.
The agency says these teams will patrol mass transit systems in the cities of Atlanta, Georgia; Philadelphia, Pennsylvania; Baltimore, Maryland; and Washington, D.C., all in the eastern United States. They will also patrol bus stations in Houston, Texas, and Amtrak rail lines on the east and west coasts of the United States.
The agency says some of the officers will wear TSA gear, while others will work undercover.
An air marshal spokesman, David Adams, says the service is trying to expand its coverage and tighten security at transit stations over the end-of-the-year holidays. He said there is no new intelligence suggesting terrorists are targeting public transportation.
