The Arkansas National Guard says it will increase patrols at its instalations to guard against possible terror attacks. Federal officials have elevated the terror risk from yellow to orange, which means a high risk of terrorist attack. Arkansas National Guard spokeswoman Captain Kristine Munn says the public can expect to see increased patrols at the gates of military installations. She says it may take longer to get on and off the grounds. Munn says she doesn`t expect Arkansas reservists and guardsmen coming home for Christmas to be affected by the orange alert status. Several busloads left out-of-state posts Saturday for homecomings in Arkansas and several more are expected.
