More than 70 professors and other faculty members at Kyoto's Doshisha University say they are "ashamed" by comments from their president, Koji Murata, in support of a set of security bills at a Diet committee hearing earlier this week.

"We, a group of university faculty members who pursue peace, are opposed to the passage of the security bills that are in violation of the Constitution," the academics said in a statement released Wednesday.

"We are ashamed from the bottom of our hearts that despite (the nature of) the legislation, the professor who serves as the president publicly expressed support for the bills."
