REDMOND, Ore. (AP) — A fire has ignited in the central Oregon city of Redmond, prompting evacuations and closing a Redmond Airport and a highway. The Bulletin reports the fire was reported Tuesday afternoon near the Redmond Air Center and was estimated Tuesday evening at between 50-100 acres. Redmond Airport director Zach Bass said the airport closed to air travel Tuesday afternoon and one operations building on airport property was evacuated.
