Tunis - Thousands gathered in the Tunisian capital on Thursday to mark the fifth anniversary of the overthrow of long serving dictator Zine El Abidine Ben Ali in the uprising that inspired the Arab Spring.Tunisians thronged Habib Bourguiba Avenue, the main thoroughfare in central Tunis and the epicentre of the country's revolution five years ago.Some attended political rallies, chanting revolutionary slogans like "Work! Freedom! Dignity!", while others listened to concerts or reminisced about the uprising.For many the anniversary raised mixed feelings, with fierce pride at the revolution tempered by concerns over continued economic problems and a rise in jihadist violence."The revolution did not help me in any way - prices went up, many young people are still marginalised," Latifa, a 40-year-old seamstress, told AFP."But I came to celebrate anyway, because the revolution brought us some democracy, and that's important."There was a heavy police presence at Thursday's celebrations, after Tunisia suffered a wave of deadly jihadist attacks last year. Ben Ali stepped down on January 14, 2011 after tens of thousands of Tunisians took to the streets to oppose his 23-year rule, and fled to exile in Saudi Arabia, where he remains.The revolution inspired similar uprisings in Egypt, Syria, Libya, Yemen and other Arab countries but only Tunisia is considered a success story of the Arab Spring.The country organised widely hailed elections in 2011 and 2014, adopted a new constitution and last year its National Dialogue Quartet - a group of four civil society organisations - was awarded the Nobel Peace Prize for helping to save its transition to democracy.Country strugglingThe 2014 elections saw the secular Nidaa Tounes led by Beji Caid Essebsi top legislative polls and in December that year Essebsi won Tunisia's first free presidential vote.But the country has struggled to revive its economy, with poverty and unemployment still high.There has also been a surge in jihadist violence since Ben Ali's overthrow, most dramatically in the attacks on the Bardo museum and on a Mediterranean resort last year that killed a total of 60 people, all but one of them foreign tourists."We are proud of the Tunisian exception, which dazzled the world. Tunisia broke once and for all with authoritarianism and tyranny," Prime Minister Habib Essid said in a statement to mark the anniversary."We are working together to fulfil the many demands of the revolution, especially the guarantee of a dignified life for all," he said, adding that "winning the war on terrorism remains an essential condition".Essid last week announced a major cabinet reshuffle, amid growing public frustration at the lack of progress in improving the economy and at continued jihadist attacks.A ceremony was to take place later on Thursday at the presidential palace in Carthage, with Essebsi giving a speech to lawmakers and other public figures.
