SANTIAGO (AFP) - A 14-year-old boy has died after being hit by gunfire during a mass protest in the Chilean capital, officials said Friday. Manuel Gutierrez died after being shot in an eastern suburb of Santiago, where tens of thousands of protesters waged a general strike on Wednesday and Thursday, supporting a months-long student protest. Around 175,000 people in dozens of towns took part in the protests, including 50,000 in downtown Santiago. Deputy Interior Minister said there were also 153 police and 53 civilians injured, and 1,394 arrested.
