The University of Arizona Police said it had deployed "chemical munitions" while telling pro-Palestinian protesters to disperse.
Police also told people to avoid the area in an update on X, formerly Twitter.
A statement from the college said: "The University of Arizona Police Department is enforcing our campus use policy to remove an unauthorized encampment. A structure made from wooden pallets and other debris was erected on campus property after 5 p.m. in violation of the policy.
"University officials issued warnings to remove the encampment and disperse. The warnings were ignored."
