Some 200 people were arrested and dozens injured as social inequality protests around Chile descended into clashes and looting overnight, police said Wednesday. In the capital Santiago, protesters set fire to a truck and stole two municipal buses, also looting supermarkets, a pharmacy and a toy store — 15 commercial premises in all. Two dozen police officers and 18 civilians were injured in clashes at 150 demonstrations that gathered some 2,300 protesters countrywide, with 195 arrests made, according to Deputy Interior Minister Manuel Monsalve. The protests started Tuesday with burning barricades around Santiago on the anniversary of a social uprising that demonstrators say has not yet yielded the desired societal change. Car traffic was disrupted, metro stations shuttered and school pupils sent home early, with 25,000 police deployed countrywide to keep the peace — 5,000 of them in the capital, where several hundred demonstrators took to the streets.
