According to multiple photos being posted to Twitter, several buildings at Syracuse University were vandalized with spray paint overnight, including some with anti-administration messages.

Some of the vandalism — such as "#1 in communication/last in free speech" and "$57,000 to take your finals" — appear to attack SU policies. Another building bears the message "Love is cursed by monogamy" — a likely reference to lyrics from Kanye West's "No Church in the Wild."

It is still unclear what the source of the vandalism was, or whether it came from students. The SU administration released the following statement Monday morning:

Every member of our campus community is entitled to his or her right to free speech, and there are many constructive ways to have your voice heard in our community. We are saddened and disappointed that anyone would attempt to exercise that right in such a destructive manner. These are a set of important and historic buildings that hold great meaning for so many of our students, faculty, staff and alumni, and to see them defaced in this manner is disheartening. The University's Department of Public Safety, in cooperation with the Syracuse City Police, is actively investigating this matter. In addition, we are already working to assess and repair the damage.

Here are some photos of the affected buildings, most via student journalists at The Daily Orange:
