SPRINGFIELD, Ill. (AP) — The Illinois National Guard is barring smartphone-toting players of “Pokemon Go” from its facilities.

National Guard officials said Friday that the public isn’t allowed on its facilities statewide to access the virtual Pokestops and gyms that are part of the game.

Guard officials said several players have appeared at the gates of Illinois National Guard facilities and training centers asking for access.

The ban covers Army National Guard, Air National Guard and Illinois Department of Military Affairs properties. It also extends to soldiers, airmen and federal and state employees working on the properties. However, an exception is being made for the Illinois State Military Museum.

Public affairs director Lt. Col. Brad Leighton said the Guard is working to have its facilities removed from the game.
