PHOENIX -- Flags on Arizona government buildings will fly at half-staff on the 12th anniversary of the Sept. 11 terrorist attacks.
Gov. Jan Brewer ordered U.S. flags at the State Capitol and all state public buildings lowered Wednesday from sunrise until sunset.
The governor also said she encourages businesses and other organizations to pay similar tribute to victims and first-responders.
Several cities around the state will also be holding their own remembrance ceremonies.
In Phoenix, officials will post an American flag that flew over Ground Zero at the World Trade Center in New York City.
More than 3,000 people were killed on Sept. 11, 2001 when terrorists hijacked three airplanes and flew them into the World Trade Center and the Pentagon. A fourth aircraft crashed in a field in Pennsylvania.
