Labor and civic groups held massive anti-government rallies in Seoul on Saturday afternoon.

The Korean Confederation of Trade Unions (KCTU), one of the nation's two umbrella groups, staged a rally along with civic groups starting at 4 p.m. near Deoksu Palace and some of the protesters clashed with police officers, with eleven of them arrested.

The KCTU accused the police of breaking into the rally, provoking the clash and violently detaining people, claiming that more than 100 protesters were taken to hospitals due to broken ribs or breathing difficulties during the process.

The police, however, said that they ordered the protestors to disperse, but they did not follow the order, pushed the police officers and hit the window of a police car with their hands.

The KCTU estimates about 100-thousand people participated in the rally, while the police said about 30-thousand attended it.

The other umbrella group, the Federation of Korean Trade Unions (FKTU), also staged a rally in Yeouido at 2 p.m., denouncing what it calls the government's "anti-labor policies."
