The day started with thousands of Chileans banging pots and pans in Santiago and other cities in the latest expression of anger over social and economic woes.
But this gave way to clashes between hooded demonstrators and riot police and soldiers in several areas of the Chilean capital, AFP observed.
Protesters again set buses on fire in downtown Santiago.
Clashes also erupted in Plaza Italia, which was ground zero of Friday's violence, and outside the presidential palace.
