| Riot police arrested students during protests, Tuesday |
Hundreds of students and workers clashed with police Tuesday. Witnesses say the protesters blocked streets and damaged property. At least 72 students were arrested and several people were injured during similar protests on Monday.
The protests have been organized by opponents of a government proposal to save money in the government pension system through reforms such as requiring an older retirement age. Officials say the pension system is facing a serious budget deficit.
Protest organizers say they are planning a wider protest Wednesday including more national groups.
