Some 15,000 Muslims rallied Tuesday to protest the new secular government's plan to curb religious education. Police moved in to quash the demonstration, and at least 13 people were injured.
The demonstrators did not have a permit for a rally, but authorities tolerated their protest for about five hours before ordering them to leave the main downtown square.
When they refused, police pushed the crowd toward side streets. Some demonstrators resisted, throwing stones at the officers, who sprayed them with pressurized water.
Four reporters and three cameramen were hospitalized with injuries from thrown rocks or police beatings. Three policemen and three protesters also were injured.
Prime Minister Mesut Yilmaz denounced the beatings and said three police officers had been suspended pending investigation.
His month-old government has proposed legislation increasing compulsory secular education from five to eight years, which would mean the shutdown of Islamic junior high schools.
