New clashes broke out in the Chilean capital Santiago on Friday despite the government's decision to call for a new constitution - a key demand of demonstrators who've been staging protests for the past month.
The latest clashes erupted after hundreds of protesters gathered in a downtown square. Riot police arrived and water cannon was used to disperse the crowds.
Chile has been in turmoil for the past four weeks as a protest over subway fares turned into a mass movement against inequality.
At least 25 people have died and thousands have been injured.
