Students at Boston College staged a walkout from classes to protest recent racial incidents on campus.
Dozens of students filed into a campus lawn shortly before noon on Wednesday and chanting "black lives matter."
The walkout was organized by the campus group Eradicate Boston College Racism after it said the college failed to respond to racist and hateful incidents on campus.
Two signs were found defaced in a residence hall over the weekend to say "Black Lives don't Matter."
College officials condemned hate and intolerance in a statement.
"Boston College condemns all acts of hate and is committed to holding any student who violates our standards accountable," said the statement. "We call upon all members of the BC community to treat each other with respect and to stand united against intolerance in any form."
Organizers of the walkout say the college teaches its students "not to be silent in times of injustices" and to fight against oppression.
Boston College is a private Catholic school west of Boston that enrolls about 14,000 students.
