Airports and seaports Border protection and increased security at airports and railways, and greater road security are also planned. The Federal Aviation Administration Tuesday announced that aircraft flying in the New York City and Washington, D.C. areas, and near Disney World in Orlando, Florida, and Disneyland in Anaheim, California, will be restricted. Unless commercial or private pilots are granted specific exemptions from air traffic controllers, no flights are allowed within a 3-mile radius around the parks or below 3,000 feet. The Transportation Security Administration, which is in charge of security at the nation's airports, announced several new measures Monday night, including random inspections of vehicles, increased canine patrols and increased law enforcement presence in and around airports. The agency will also be putting up temporary signs inside airports asking the public to be aware of the increased threat level and to report unattended bags and suspicious behavior. The Coast Guard will protect offshore petroleum sites near large coastal population centers, and security is being increased at chemical facilities, nuclear power plants, key electrical grids, bridges and subways. There will also be increased monitoring of diseases and food security, Homeland Security said. The Agriculture Department is alerting food producers to step up their security -- such as inspecting all vehicles and escorting all visitors -- and is helping monitor feedlots, stockyards, and import and storage areas. Imported food will also come under increased scrutiny by the Department of Health and Human Services, which is asking health departments and medical care providers to report unusual diseases or disease patterns. ---------------------------------------------- The entire article can be read on cnn.com Just click on the raised threat level story..
