The U.N. Human Rights Agency is calling on Spanish authorities to investigate the violent riots linked to Sundays Cataloniaâ€™s independence referendum.
On Monday morning the agencyâ€™s high commissioner urged Spanish authorities to investigate the violence carried out by riot police on voters.
Reports claim police used batons, rubber bullets, and physically attacked those in support of the referendum.
An agency spokesman says an investigation could help calm tensions in the region.
Spanish Foreign Minister Alfonso Dastis denies that police involvement during the referendum was excessive.
