Serbia: Disputed Remembrance - On June 28, 1914, Serbian nationalist Gavrilo Princip fired the shot that killed Archduke Franz Ferdinand, the heir to the Austro-Hungarian throne. That assassination led to the outbreak of the First World War. Even today, many in Serbia and Serbian areas of Bosnia still regard Princip as a national hero. With the 100th anniversary of the assassination approaching, several memorials to Princip have been erected in Sarajevo. We pay a visit to Belgrade and the Bosnian capital of Sarajevo to examine the controversy that still surrounds the fateful assassination. Crimea: Deceptive Dream - In March, Russia annexed the Crimean Peninsula in the Black Sea. Moscow lured Crimeans with big promises and spoke of a better life. But a few months after Russian troops occupied the peninsula, everyday life has returned. Only a few ferries connect the Russian mainland with Crimea, and a planned bridge will take years to build. At the entrances to the ferries, lines of frustrated Russian vacationers and Crimean residents back up for kilometers. Six million tourists visited the Crimea last year; this year, the number will only be a fraction of that. Both the Ukrainians and Western cruise ships are staying away. And the currency shift from hrynvias to rubles is making everything more expensive -- in some cases, by 50 percent! A report from the annexed peninsula. Germany: Misery among Migrant Workers - Many Germans fear that the country's social welfare system could be abused by EU citizens from Romania and Bulgaria. But it's often the migrant workers from those countries who are being exploited. The conservative Bavarian party, the CSU, tried to whip up antagonism towards Eastern Europeans coming to Germany, saying they were only interested in cashing in on welfare benefits. Since the beginning of the year, Bulgarians and Romanians have been allowed to work without restrictions across the EU, including in Germany. If they have residency here, they're entitled to child allowance and, in some cases, basic welfare benefits. But many of them aren't aware of these regulations and are being exploited as day laborers. Sweden: A Museum of Sound - What did everyday life used to sound like? Do you remember what a whistling tea kettle sounded like? And what about the noise of a propeller plane? Sounds are part of history and Thorsten Nilsson is fascinated by everything that clangs, grinds, clicks and roars. But each year, more and more old machines and devices become extinct forever. That's why he's set out on a quest to record these endangered industrial sounds and preserve them for posterity.
