Hundreds of Greek students have held a fresh demonstration outside the parliament in the capital Athens to protest against a series of recent austerity measures approved by the government.
The students protested on Saturday against the spending cuts in the country's education system as well as wage and job cuts affecting their families.
Hundreds of police forces tried to disperse the students and push them away from the parliament building.
Earlier on Friday, angry Greek protesters, including students, staged rallies and clashed with riot police in Athens.
The Greek parliament approved a new round of austerity measures early Monday in return for a new eurozone bailout, worth 130 billion euros, from international loan providers for the debt-stricken country.
The latest measures include 300 million euros in pension cuts and a 22 percent reduction in minimum wages from about 750 euros a month.
Despite the austerity cuts and the bailout funds, which have been aimed at stimulating growth for the troubled Greek economy, the country has been in recession since 2009.
Many anti-government demonstrations have been held against austerity measures in Greece since early 2011. Many of the rallies have at times turned violent, leaving scores of protesters injured.
