Portions of Scott Air Force Base in southwestern Illinois are closed as authorities investigate a suspicious package received at the installation's mail center.

Air Force Lt. Benjamin Garland says the package uncovered Wednesday morning prompted precautionary evacuations of the base's education center, bowling alley and other services near the mail center.

Garland says he has no immediate information about any injuries or the nature of the package's contents.

Scott Air Force Base is near Mascoutah (muh-SKOO'-tuh), about 25 miles east of St. Louis.
