SANTIAGO, Chile (AP) - Bands of young people hurling firebombs and stones clashed with police outside Chile's congress on Tuesday after thousands of students and workers staged a protest march before President Sebastian Pinera's final state of the nation speech.
The president was not exposed to the violence around the legislature, which is in the port city of Valparaiso.
Authorities said more than 130 people had been arrested and two police motorcycles were set on fire.
About 10,000 people marched peacefully earlier demanding wide-ranging expansion of free education.
During his speech, President Pinera urged legislators not to give into the demands that all education be made free, saying the state shouldn't pay for those who can afford to pay for school.
