Seoul: A disability rights advocacy group staged a surprise "bus-boarding" protest in central Seoul during the morning rush hour Friday, causing partial road closures and severe traffic congestion.

According to Yonhap News Agency, about 20 members of the Solidarity Against Disability Discrimination began the protest at the Gwanghwamun Station intersection at 8:10 a.m. The activists were calling for the enactment of a new bill on guaranteeing mobility rights for disabled people and the expansion of disabled-friendly low-floor buses.
