Military police from the special unit Chope advance toward protesters late on June 19, 2013 in the center of Niteroi, 10 kms from Rio de Janeiro. Protesters battled police late on June 19, even after Brazil’s two biggest cities rolled back the transit fare hikes that triggered two weeks of nationwide protests. The fare rollback in Sao Paulo and Rio de Janeiro marked a major victory for the protests, which are the biggest Brazil has seen in two decades.
