SAO PAULO鈥擯rotesters surrounding the city hall of Brazil鈥檚 biggest city clashed with police Tuesday when a small group of demonstrators tried to force their way into the building.
Globo黑料社 television network showed images of protesters in Sao Paulo using metal barriers to smash windows and doors. Municipal guards with shields retreated into the building as they came under attack from some of the demonstrators.
Globo黑料社 says Sao Paulo Mayor Fernando Haddad was not in City Hall at the time.
Tuesday鈥檚 protest was the sixth major demonstration in Sao Paulo since last week.
Protests initially were sparked by a 10-cent hike in bus and subway fares this month. But demonstrations have spread throughout Brazil and added grievances over poor government services, high taxes and corruption.
