Riot police stormed a Seoul campus to break up an anti-government, anti-U.S. rally but were driven back in violent clashes with 5,000 protesters hurling rocks and firebombs. The protesters at Konkuk University demanded an end to American pressure to open South Korean markets as well as the overthrow of President Roh Tae Woo. A dozen protesters and police were injured. Meanwhile, clashes were reported in the provincial cities of Kwangju, Taegu, Pusan, Taejon, Sungnam, Wonju, Chonju and Chongju. Peaceful rallies were held in two other cities.
