Waving the flag: On Feb. 17, Kosovo celebrated the one-year anniversary of its self-declared independence from Serbia. Thousands of Kosovars took to the streets, and restaurants in the capital, Pristina, offered free champagne. In the city's Mother Teresa Square, vendors sold Kosovo's blue and yellow flag, as well as flags of Albania and the United States, both strong backers of Kosovo's independence.

The mood may have been largely celebratory, but Kosovo faces many challenges ahead.
