BELFAST: Violence flared for a second night around traditional Orange Day parades in Northern Ireland, with police coming under attack from petrol bombs, fireworks, stones and bottles and responding with water cannon.

One police officer was engulfed in flames when struck by a petrol bomb, but it was quickly extinguished by colleagues. The officer remained on duty after being examined by medical personnel, a spokesman said.

Thousands of pro-British Protestants march every summer in the British province, a regular flashpoint for sectarian violence as Catholics, many of whom favour unification with Ireland, see the parades as a provocation.

Violence between the two religious groups still sometimes flares since a peace deal was signed in 1998, which largely ended three decades of strife. Much of Belfast remains divided along religious and nationalist lines.

The Orange Order, which organises marches to mark the 1690 victory at the Battle of the Boyne by Protestant Prince William of Orange over Catholic King James of England, was angered this year when authorities ruled they could not walk along a stretch of road that divides the two communities.

That sparked violence on Friday evening, after tens of thousands of Orange Order marchers, wearing orange sashes and waving British flags, paraded at more than a dozen venues across Northern Ireland.

A total 32 police were injured on Friday night in what Chief Constable Matt Baggott described as “shocking and disgraceful” violence, including head, eye and leg wounds.

Another 400 reinforcements were being brought in from Britain as trouble continued through the weekend. More than 20 people have been arrested.

Brazil: Brazilian President Dilma Rousseff ended her near-silence about days of massive, violent protests, saying in a prime-time TV broadcast Friday that peaceful demonstrations were part of a strong democracy but that violence could not be tolerated. She promised to improve public services and hold a dialogue with protest leaders.

But it remained unclear exactly who could represent the massive and decentralized groups of demonstrators taking to the streets, venting anger against woeful public services despite a high tax burden.

“I’m going to meet with the leaders of the peaceful protests, I want institutions that are more transparent, more resistant to wrongdoing,” Rousseff said in reference to perceptions of deep corruption in Brazilian politics, which is emerging as a focal point of the protests. “It’s citizenship and not economic power that must be heard first.”

Though offering no details, Rousseff said that her government would create a national plan for public transportation in cities — a hike in bus and subway fares in many cities was the original complaint of the protests. She also reiterated her backing for a plan before congress to invest all oil revenue royalties in education and a promise she made earlier to bring in foreign doctors to areas that lack physicians.

The leader, a former Marxist rebel who fought against Brazil’s 1964-1985 military regime and was imprisoned for three years and tortured by the junta, pointedly referred to earlier sacrifices made to free the nation from dictatorship.

“My generation fought a lot so that the voice of the streets could be heard,” Rousseff said. “Many were persecuted, tortured and many died for this. The voice of the street must be heard and respected and it can’t be confused with the noise and truculence of some troublemakers.”

She’d been widely criticized for being all but invisible amid the protests and failing to engage with the people who were demanding her government’s attention.

Edvaldo Chaves, a 61-year-old doorman in Rio’s upscale Flamengo neighborhood, said he found Friday’s speech convincing.

“I thought she seemed calm and cool. Plus, because she was a guerrilla and was in exile, she talks about the issue of protests convincingly,” Chaves said. “I think things are going to calm down. We’ll probably keep seeing people in the streets but probably small numbers now.”

But Bruna Romao, an 18-year-old store clerk in Sao Paulo, said Rousseff’s words probably wouldn’t have an impact.

“Brazilians are passionate,” she said. “We boil over quickly but also cool down fast. But this time it’s different, people are in full revolt. I don’t see things calming down anytime soon.”

Trying to decipher the president’s reaction to the unrest had become a national guessing game, especially after some 1 million anti-government demonstrators took to the streets nationwide Thursday night to denounce everything from poor public services to the billions of dollars spent preparing for next year’s World Cup soccer tournament and the 2016 Olympics in Brazil.

The protests continued Friday, as about 1,000 people marched in western Rio de Janeiro city, with some looting stores and invading an enormous $250 million arts center that remains empty after several years of construction. Police tried to disperse the crowd with tear gas as they were pelted with rocks. Police said some in the crowd were armed and firing at officers.

Local radio was also reporting that protesters were heading to the apartment of Rio state Gov. Sergio Cabral in the posh Rio neighborhood of Ipanema.

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.

The fringe parties have taken to exception to the major political parties’ decision to form the CJ-led election government. The dissenting parties have been staging a series of protest programs demanding the termination of the 11-point agreement signed by major political parties and 25-point signed for removing constitutional obstacles.

Security situation in and around the Singha Durbar has been beefed up citing possible clashes.
