Students at a Catholic college in Rhode Island have occupied the president's office over allegations of racism on campus.

At least 20 Providence College students sat in the office of the Rev. Brian Shanley on Tuesday and planned to stay until he signed an agreement of commitment.

The students said Shanley hasn't responded to a list of demands they presented to the school's administration in December.

Associate Vice President Steven Maurano told the Providence Journal that Shanley couldn't sign the group's agreement because some of the demands, such as curriculum changes, cannot be made without a discussion with faculty.

Providence College officials haven't allowed media on campus.

About 75 to 100 Providence College students staged a demonstration in November calling on Shanley to address racism on campus.
