Hesham Abdel-Baky, president of N.C. State's Muslim Student Association, said he has witnessed more support for Arab students than abuse, particularly from campus administrators.
But Abdel-Baky added that there have been several racially and religiously motivated harassment incidents on campus.
"One of our covered women -- the Muslim women who wear the veil -- was spit at the day of the attack," he said.
"Another said she had small pebbles thrown at her."
Abdel-Baky said he still recommends that veiled Muslim women walk to class in pairs, even a month after the attack.
Tom Stafford, vice chancellor for student affairs at N.C. State, said several Arab students have withdrawn from the university for fear of racial or religious harassment in the wake of the terrorist attacks.
But Stafford also said N.C. State administrators have been going to extra lengths to ensure the safety of Arab and Muslim students.
"We will not tolerate discrimination based on racial or religious background," he said.
To demonstrate their stance, administrators placed the university's harassment policy in a prominent location on N.C. State's home page.
