    Experts in Chile have warned that the daily use of tear gas by police could have serious side effects.

    For nearly seven weeks, protesters have been demonstrating - often leading to clashes with security forces.

    The rallies began in October when the government decided to increase metro fares. That proposal has since been reversed.
