Subway train operators, along with activists from social movements, clash with riot police in front of the Ana Rosa metro station, in an ongoing subway strike, in Sao Paulo, Brazil, Monday, June 9, 2014. Authorities are deeply worried about the strike because the subway is the main means of transportation for World Cup fans scheduled to attend Thursday's opening match when Brazil takes on Croatia. The stadium is about 20 kilometers (12 miles) east of central Sao Paulo, where most tourists stay. (AP Photo/Mario Angelo) less
