Tunisia two years after revolution

Two years ago this month, a young Tunisian man named Mohammad Bouazizi set himself alight, sparking a revolution in his country and a wave of Arab uprisings.

Tunisia's so-called 'Jasmine Revolution' was peaceful and many were optimistic about the country's transition to democracy.

The BBC's Lyse Doucet, who reported from Tunisia during the revolution, has been back there to find out what has been achieved.
