Rallies have marked the first anniversary of the event that triggered the Arab Spring uprisings.

Young Tunisian Mohamed Bouazizi set himself on fire after he was banned from selling fruit to earn a living.

His extreme act sparked the first open protests against the Tunisian government, which in turn set off demonstrations around the Arab world.
