CBC News: The World This Weekend

The latest developments in a tumultuous afternoon of anti-NATO protests in Chicago -- including striking views of veterans throwing their medals away and two Canadians leading the parade through the downtown. There's lighter news too: Love Motels in Rio de Janeiro have prepared for a large legitimate guest contingent -- people attending the 20th anniversary of the Earth Summit. Motel owners even installed closets. But inhospitable 'real' hotels have scared away many prospective Summit visitors. Hear the whole story tonight.

A bombing in Italy kills a teenage girl and a local bishop is booed by students who are tired of corruption and mafia-related violence. India's Rupee has fallen to its lowest level ever relative to the US dollar and India's Finance Minister blames the crisis in Greece. And -- Canada's lighthouses are dimming en masse. You have until the end of May to petition to take over ownership of any of the Federal Government's 500 surplus lighthouses. We visit one such iconic structure on the shore of Lake Winnipeg and hear some stories from those who want to save it.

When your instrument is church bells, how do you improve without driving everybody crazy? The next generation of ringers is coached in the art at Knox Metropolitan United in Regina. And -- an agricultural valley in Israel has the densest population of barn owls in the world -- raised and housed to kill rodent pests. Convinced by the success, Palestinians and Jordanians are bringing the project across the border. Queen Elizabeth II first saw the RCMP musical riders when she was eleven and has never forgotten. Tonight they ride in her Diamond Jubilee ceremony, by her invitation of course.

Schools in Ontario are being closed down as the Province consolidates facilities in order to save money. One school in Peterborough is fighting back big time -- and raising money for a legal challenge. And we have a story from Mexico on how drug cartels are stifling stories in the media, and how journalists are continuing to do their work in one of the most dangerous environments in the world.

Voters in France and Greece have directed their governments away from Eurozone austerity policies. Socialist Francois Hollande is the new French President-elect and in Greece, the two pro-austerity parties no longer hold a majority after today's elections. As well on the show: a major cause of stomach cancer can be pre-emptively treated with antibiotics; and a dramatic picture of crime and retribution in rural Bolivia.

Children in hospitals have many anxieties which can be soothed with the therapeutic humour and distraction provided by special professionals -- hospital clowns. Our report follows a group of hospital clowns visiting a Children's Hospital in Halifax. Parents and children agree: what they do works. Now, can they standardize the training and be officially accepted as health care practitioners? Also -- a young mother with a Canadian Residency Permit is in a Russian jail. She is part of the "all girl" punk band Pussy Riot -- and they are facing sentences of up to seven years after they took over the altar of a Moscow Cathedral for an an anti-Putin "prayer". Amnesty International says they are Prisoners of Conscience. Ottawa has said nothing. All this and much more on tonight's show...

A former executive with SNC Lavalin is in jail in Switzerland. Riahd Ben Aissa was head of Construction operations in Tunisia and Libya. He is facing fraud and corruption charges. We have the latest from our joint investigation with Swiss public broadcaster SRG SSR. And a translation 34 years in the making... the Old Testament finally translated into Inuktitut and it took patience, diligence and imagination: for instance a 'camel' becomes "an animal good at walking in the sand, with one or two mountains on its back".

All the latest on the headlines today, and -- a look at post-revolution Tunisia, which on the street looks a lot like pre-revolution Tunisia, with a seized-up economy and a crippling unemployment rate. With parliamentary elections still a year away, there is a stalemate between theocratic conservatives and leftist unionists, each unable to effect their programs. And there are no prospects for even the best-educated young people. Also: documentary film-makers talk about the future of their industry in Canada; and a short biography of an unsung Canadian -- one of the most-sought after opera vocal coaches in New York City.

Nicolas Sarkozy taken down a notch by French voters -- can the tenacious fighter manage a comeback against Francois Hollande in two weeks? And in Montreal -- a blur of daily protests merge into a crowd of thousands, as a week of agitation is capped by a huge Earth Day march. And we look at cross-border human egg shopping. You can do it by catalogue -- despite the fact that such a marketplace is illegal within Canada.

Raffi Torres responds to his suspension, and those for and against the 25 game time-out have their say. Later on in the show -- a Saskatchewan lab on the trail of the mysterious cause of death of thousands of British Royal Navy sailors in the Caribbean during the late Eighteenth and early Nineteenth Centuries... And a new Cirque Du Soleil show based on The Tempest with women in the lead roles and doing all the heavy lifting.

On the show, a journalist in Kabul brings us an eye-witness account of the Taliban urban assault this afternoon. And in France -- Francois Hollande is looking to unseat President Nicolas Sarkozy. Hollande is admired for his deft wit and Sarkozy known for his punishing prowess in debate. Their upcoming debates are considered must-see TV in France. And -- In 1982, with Canada's Constitution repatriated, a Toronto student sloshed the original document with red paint. Tonight we have memories from all those involved -- the vandal, the archivist who restrained him and called for help, the restoration team which furiously tried to remove the stain – and speculation on whether the stain itself, thirty years later, is now a part of history worth conserving.

Tonight, the U.N. Security Council agrees -- they will ask Syria to take U.N. observers to mediate the ceasefire. Also tonight -- a story about the distress call from the Titanic: there is evidence it was first heard by a 14 year-old apprentice while the main operators were on a break at their station at Cape Race Newfoundland. And -- two Toronto students have invented a simple, inexpensive application which can "speak" for people who can't communicate orally. Twelve thousand people around the world are using it already.

Tonight the possibility of peace in Syria is in tatters as the government turns viciously again on its citizenry in Homs, and Syrian opposition leaders refuse to sign on to the plan for a mid-week cease fire. The Pope speaks on Syria in his Easter sermon. Also in the show -- a fine art tour of Last Suppers. Da Vinci's depiction is the most famous view of that event, but there are at least ten other significant versions by other artists in Florence alone, and they are often more accessible and in better condition than Da Vinci's. This and more tonight...

A rowing row on the Thames... the annual competition between Oxford and Cambridge Universities is derailed by a mid-river protestor. Also on the show: a lament for a California State Park slated to close by July. Seventy of the state's 209 parks were scheduled to close as a money-saving measure, but sponsors have been found for nine of those. For the rest, the wholesale closures are prompting soul-searching about the ignoble fate of a rich natural and historic legacy. And later, researchers are looking for new ways to diagnose and treat concussions in children.

Aung San Suu Kyi takes Burma into a new era -- the celebrated Nobel Peace Laureate wins a seat in parliament where she will sit opposite military representatives responsible for her years spent under house arrest. And in Ottawa tonight, the Juno Awards continue. Spread across the categories is a sprinkling of trendsetters mining many ultra-hip subgenres. But where is the vibrant new wave of Quebec superstars like singer Coeur de Pirate? Despite having won the equivalent of a Grammy in France for Best Song, she is confined to only "Francophone" categories here at home. The World This Weekend visits the Juno's two solitudes.
