A molotov cocktail was launched in front of the US consulate in Rio de Janeiro late Friday in protest of the arrival of President Barack Obama, the O Globo newspaper in Rio reported. Military police reacted by firing rubber bullets into the gathering of 200 at around 18:30 local time. A CBN news reporter suffered a minor injury from the shots and traffic was blocked.

"They came after us with clubs and tear gas and attacked," according to protestor Thiago Hastenheiter. "They chased us through the streets and started firing rounds of rubber bullets."

Police major Fabio Alessandro of the 13th Batallion of Rio's military police said that the protestors, all left leaning social movements associated with the Socialist Workers Party, PSTU, did not have a permit to protest near the consulate along Avenida Rio Branco and had refused to disperse from the area. They wore the ubiquitous Che Guevera T shirt and carried American flags that said Go Home Obama. Most of the protests had been peaceful until two home-made molotov cocktails were let loose in the direction of the Consulate. A guard at the Consulate was partially burned and was sent to the emergency room at Souza Aguiar Hospital.

Fourteen protestors have been arrested.

Japan has confirmed the presence of radioactive iodine contamination in food products from near a crippled nuclear plant and is considering whether to order a halt to the sale of such products from the area, the U.N. nuclear body said on Saturday.

• Rescuers found them after responding to their shouts

Extraordinary news emerged from the tsunami coast today when police reported they had found an 80-year-old woman and a 16-year-old boy still alive under rubble in a tsunami-smashed city.

The report was greeted with scepticism at first following claims on Saturday that a young man had been found alive in his house after clinging to life for eight days - when in fact he had returned to his home from a shelter.

But police in the Mikako prefecture were insisting that there was no mistake about the two people found alive under rubble today.

Children as young as four are being given Ritalin-style medication for behavioural problems in breach of NHS guidelines, the Guardian has discovered, prompting the leading psychological society to call for a national review.

Family-based therapy is recommended for treating children with ADHD (attention deficit hyperactivity disorder), with prescription drugs used only for children over six years old and as a last resort.

The figures, based on data from 479 GPs, show prescription rates were highest for children aged six to 12, doubling to just over eight per 1,000 in the five years up to 2008. Children aged 13 to 17 had the second highest rate at six per 1,000, while those aged 25 and over had less than one per 1,000.

Concern is greatest over children under six who should not be receiving drugs at all, says the National Institute for Health and Clinical Excellence (Nice).

There was plenty of anger but no violent confrontation after a moving cordon of police kept neo-Nazi and anti-racist groups apart at parallel rallies in downtown Calgary on Saturday.

About 200 members of Anti-Racist Action Calgary gathered at Calgary city hall after word that the neo-Nazi group, Blood of Honour, was planning a march.

"We're here to celebrate our diversity - the things that make us the same and different at the same time. We're also here to protest racism, discrimination in its different forms and most explicitly in this case the violent neo-Nazi gangs that exist within our city," said Jason Devine, a spokesman for ARA Calgary.

But the 16 members of Blood of Honour, chanting "White Pride Worldwide" found their paths blocked by Calgary Police officers, including riot squad members, who cordoned off several streets in the downtown.

"Charge me. Arrest me. It would be false imprisonment. Just do it," shouted one of the Blood of Honour group to a police officer.

Helen Thomas is not sorry, nor were the comments that ended her career accidental.

"I knew exactly what I was doing - I was going for broke," she told Playboy in the magazine's April interview. "I had reached the point of no return. You finally get fed up ... I finally wanted to speak the truth."

Thomas, of course, left her perch as the dean of the White House press corps last year after telling a rabbi and blogger that Jews should "get the hell out of Palestine" and "go home" to "Poland, Germany and America and everywhere else." Her family is Lebanese and she grew up in the Detroit area, home to one of the country's densest populations of Arab Americans.

More than 100 anti-war protesters, including the man who leaked the Pentagon Papers, were arrested outside the White House on Saturday in demonstrations marking the eighth anniversary of the U.S.-led war in Iraq.

The protesters, some shouting anti-war slogans and singing "We Shall Not Be Moved," were arrested after ignoring orders to move away from the gates of the White House. The demonstrators cheered loudly as Daniel Ellsberg, the former military analyst who in 1971 leaked the Pentagon's secret history of the Vietnam War that was later published in major newspapers, was arrested and led away by police.

Similar protests marking the start of the Iraq war were also planned Saturday in Chicago, San Francisco and other cities.

The demonstration in Washington on Saturday merged varied causes, including protesters demanding a U.S. military withdrawal from Iraq and Afghanistan as well as those supporting Bradley Manning, the jailed Army private suspected of giving classified documents to the website Wikileaks.

One chant that was repeated was: "Stop the War! Expose the Lies! Free Bradley Manning!"

There was little talk of the U.S. missile strikes against Moammar Gadhafi's forces in Libya on Saturday, part of an international effort to protect rebel forces.

Manning is being held in solitary confinement for all but an hour every day at a Marine Corps brig in Quantico, Virginia. He is given a suicide-proof smock to wear to bed and is stripped naked each night. On Sunday, a protest will be held in Quantico, outside the brig where Manning is being held.

Ellsberg has publicly defended Manning, calling him a "brother," and Wikileaks.

A 70-year-old man was stoned to death with a rock stuffed in a sock by a younger friend who alleged the victim made unwanted sexual advances, authorities said.

According to the criminal complaint, John Thomas, 28, of a Philadelphia suburb, told police he killed Murray Seidman of nearby Lansdowne because the Bible refers to stoning homosexuals.

"I stoned Murray with a rock in a sock," Thomas told police, according to the criminal complaint. Thomas was arrested and charged with murder Friday.

According to the complaint, "John Thomas stated that he read in the Old Testament that homosexuals should be stoned in certain situations. The answer John Thomas received from his prayers was to put an end to the victim's life. John Thomas stated that he struck the victim approximately 10 times in the head. After the final blow, John Thomas made sure the victim was dead."

"He is a deeply religious man. Or so he says," said Lansdowne Police Chief Dan Kortan.

Government payouts - including Social Security, Medicare and unemployment insurance - make up more than a third of total wages and salaries of the U.S. population, a record figure that will only increase if action isn't taken before the majority of Baby Boomers enter retirement.

Even as the economy has recovered, social welfare benefits make up 35 percent of wages and salaries this year, up from 21 percent in 2000 and 10 percent in 1960, according to TrimTabs Investment Research using Bureau of Economic Analysis data.

"The U.S. economy has become alarmingly dependent on government stimulus," said Madeline Schnapp, director of Macroeconomic Research at TrimTabs, in a note to clients. "Consumption supported by wages and salaries is a much stronger foundation for economic growth than consumption based on social welfare benefits."

The economist gives the country two stark choices. In order to get welfare back to its pre-recession ratio of 26 percent of pay, "either wages and salaries would have to increase $2.3 trillion, or 35 percent, to $8.8 trillion, or social welfare benefits would have to decline $500 billion, or 23 percent, to $1.7 trillion," she said.
