Tunisia is marking the one-year anniversary of the revolution that ended the dictatorship of Zine El Abidine Ben Ali - and sparked uprisings around the Arab world - with prudent optimism.
Worries over continued high unemployment cast a shadow over Tunisians' pride at transforming their country. Now a human rights activist is president, and a moderate Islamist jailed for years by the old regime is prime minister at the head of a diverse coalition.
The death of a fruit vendor who set himself on fire prompted protests that spread around Tunisia, unleashing years of pent-up frustration and anger. Under pressure from the street, Ben Ali fled to Saudi Arabia on January 14.
Leading Arab dignitaries are joining Tunisia's leaders to commemorate Saturday's anniversary.
