Arab uprisings: Tunisian rapper asks what has been gained

On 17 December 2010, Tunisian vegetable seller Muhammad Bouazizi set himself on fire.

His death sparked a wave of protests across the Arab World - from Tunisia all the way to Syria.

To coincide with the third anniversary of Mr Bouazizi's self-immolation, BBC News returned to the countries affected by the uprisings, to assess the resulting change in the region.

In Tunisia itself, after a rocky start to the year when members of the opposition were murdered, the Islamist majority and their secular opponent have formed a caretaker government and are writing a new constitution, with a second democratic election planned.

But some say that the grievances that led to the initial revolution have still not been properly dealt with.

Rapper Mohamed Amine Hamzaoui told BBC News he was happy that his country had sparked the flames of revolution, but he did not see that much had changed.
