Yesterday (Weds) Chilean students took once more to the capital's streets to protest for free education for all. The demonstration which quickly turned violent, is the latest in several eventful days of action over the past year, known as the 'Chilean Winter'. 

Meeting once again in Santiago's Plaza Italia and marching through the city, the students were met by hundreds of police officers in riot gear. Images show that water canons and tear gas were used against protesters very soon after the demonstration started. 

Two buses were set on fire on General Bustamante between Marin and Ramón Carnicer, as the crowd attempted to march carrying banners and placards. 

The protest was denied permission from the authorities, with those in charge citing the damage caused during the other demonstrations as the reason for the ban. 

The last protest on June 28 caused over a million pesos of damage in Santiago Centro and was met with police violence against the mainly young people taking part. 

Student demonstrations have been taking place in Chile for over a year. In April as many as 50,000 students took to the streets, with some altercations taking place between protesters and the authorities after a police booth was allegedly set on fire. Smaller protests held in other cities were conducted peacefully.

Despite a speech made by the Chilean President Sebastian Pinera, outlining tax reforms expected to raise around $700m (£433m), much of which will be funnelled to the country's education system, students organisations believe this to not be enough and yesterday's action is the latest attempt to force the government to concede.
