BRASILIA, Brazil —
Other protests broke out in the country's biggest city, Sao Paulo, where traffic was paralyzed but no violence reported, and in Fortaleza in the country's northeast. Demonstrators were calling for more mobilizations in 10 cities on Saturday.
The National Conference of Brazilian Bishops came out in favor of the protests, saying that it maintains "solidarity and support for the demonstrations, as long as they remain peaceful."
"This is a phenomenon involving the Brazilian people and the awakening of a new consciousness," church leaders said in the statement. "The protests show all of us that we cannot live in a country with so much inequality."
Rousseff had never held elected office before she became president in 2011 and remains clearly uncomfortable in the spotlight.
She's the political protege of former President Luiz Inacio Lula da Silva, a charismatic ex-union leader whose tremendous popularity helped usher his former chief of staff to the country's top office. A career technocrat and trained economist, Rousseff's tough managerial style under Silva earned her the moniker "the Iron Lady," a name she has said she detests.
"The government has to respond, even if the agenda seems unclear and wide open," Marlise Matos, a political science professor at the Federal University of Minas Gerais, said before Rousseff spoke. "What I'd like to see as a response is a call for a referendum on political reform. Let the people decide what kind of political and electoral system we have."
Brazil watchers outside the country were puzzled by the government's long silence amid the biggest protests in decades, although Peter Hakim, president emeritus at the U.S.-based Inter-American Dialogue think-tank, said he appreciated the complicated political picture, especially with protests flaring in some areas where political opponents to Rousseff hold sway.
