The state of Indiana is on alert following this morning's apparent terrorist attacks at the World Trade Center and Pentagon. State officials have tightened security at courts and government offices. Alden Taylor is a spokesman for the State Emergency Management Agency. Taylor says capital police who patrol the grounds of the Indiana Statehouse and adjoining government buildings have been advised to watch for any suspicious activity. All outgoing flights from Indiana's airports have been canceled by the Federal Aviation Administration, stranding thousands of passengers in Indianapolis, Fort Wayne, South Bend and Evansville. Meanwhile...an FBI spokesman in Indianapolis knows of no suspicious incidents in Indiana today that may be linked to terrorism. Spokesman Doug Garrison says the Federal Protective Services in Indianapolis heightened security at the city's Federal Building after two planes crashed into the World Trade Center in New York this morning. Garrison says local FBI agents think they may be called to assist the agency in New York or Washington, DC. He says they're preparing to respond if necessary, and they're hoping and praying nothing happens in Indiana.
