DES MOINES, Iowa (AP) — Iowa Gov. Terry Branstad is ordering flags at state government buildings and other sites to be flown at half-staff to honor those who died in the Sept. 11, 2001, terrorist attacks. Branstad called for the flags to be lowered from 8 a.m. to 5 p.m. at public buildings, grounds and other facilities throughout the state. Individuals, schools and businesses also are encouraged to fly flags at half-staff during this period as a show of respect. The Sept. 11 attacks killed nearly 3,000 people at the World Trade Center, the Pentagon and a Pennsylvania field.
