Nebraska Governor Dave Heineman is ordering flags at state government buildings and other sites to be flown at half-staff to honor astronaut Neil Armstrong and U.S. Ambassador Chris Stevens and three other Americans killed in an attack in Libya.
The governor is calling for the flags to be lowered on Friday in memory of Armstrong, the first man on the moon. He died on Aug. 25 at the age of 82.
Heineman says flags will be flown at half-staff on Sunday to honor Stevens and three American members of his staff. They were killed on Tuesday when the U.S. consulate in Benghazi came under attack by a mob.
Stevens is the first U.S. ambassador to be killed in an attack since 1979, when Ambassador Adolph Dubs was killed in Afghanistan.
