Chile's president declared a state of emergency in the capital Santiago on Friday night and gave the military responsibility for security after a day of violent protests over increases in the price of metro tickets
Throughout Friday, protestors clashed with riot police in several parts of the city and the subway system was shut after attacks on several stations.
Violent clashes escalated as night fell, and the ENEL power company building and a Banco Chile branch, both in the city center, were set on fire and several metro stations hit with Molotov cocktails.
The Santiago Metro, at 140 kilometers (90 miles) the largest and most modern in South America, is expected to remain closed this weekend and could reopen gradually next week.
Closure of the metro forced many Santiago residents to walk home, sometimes long distances, resulting in scenes of chaos. (AFP)
