Ukraine: Lviv's Mayor - For many in Ukraine he's much like a pop star. Andriy Sadovyi has been mayor of the city of Lviv since March 2006 and has a burning desire to see his country reunited. Under the 46-year-old's leadership, the city of Lviv has become a role model for all of Ukraine. The electrical engineer has built up the infrastructure and lured investors to the city. He says the key to his country's future is to give municipalities more authority. Sadovyi feels the government in Kiev should relinquish central powers in cases where local authorities can deal with issues better. Norway: Debate over a Memorial - Three years after the massacre by right-wing extremist Anders Breivik, Norway is searching for the proper way to commemorate the 77 victims. But survivors and families of victims can't agree. When Breivik created a bloodbath on the island of Utoya, it sent shockwaves across the entire nation. Now an artist wants to memorialize the tragedy by cutting a channel though a neighboring island to symbolize the wound Breivik inflicted on the nation. Critics call the proposal a mutilation of nature and worry that a divided island would become a macabre tourist attraction. Local residents mainly want to lay the past to rest. Romania: The Sewer Dwellers of Bucharest - An estimated 6,000 homeless people live in the network of sewers and tunnels beneath the streets of Bucharest. Many were born underground and are now having children themselves. It's a world of its own, a world full of drugs, disease and poverty that's developed beneath the capital. The sewer dwellers live in the tunnels, canals, and sometimes in caves they've dug themselves, because they have nowhere else to go. Many have tuberculosis, hepatitis or are HIV positive, and live in tightly organized groups. Children in particular sniff paint to escape their misery -- at least for a while. Scotland: A Nation Divided - The countdown is on. There's just two-and-a-half months left until Scots cast their ballots on whether to stay in the UK or become an independent country. Recent polls indicate that around 30 percent of Scots are still undecided about how they'll vote. Brussels has already made it clear that should Scotland choose to become independent it wouldn't automatically qualify to stay in the EU. But other practical issues remain unclear and are dividing the Scottish people.
