TUNIS (AFP) - Tunisia on Wednesday saw its first deadly attack on foreigners since the 2010-2011 uprising that toppled president Zine El Abidine Ben Ali after 23 years in power.
But the country that gave birth to the Arab Spring has seen a sharp rise in Islamist militancy which has left dead about 60 police and military personnel.
A timeline of unrest:
Dec 17: A young university graduate who has only been able to find work as a fruit seller burns himself to death to protest police harassment and unemployment in the central town of Sidi Bouzid, unleashing rioting which spreads across the country. Some 338 are killed.
Jan 14: Under massive popular pressure Ben Ali flees to Saudi Arabia.
Feb 25: Police stations are attacked as anti-government demonstrations force Ben Ali's last prime minister, Mohamed Ghannouchi, to resign. He is replaced by veteran politician Beji Caid Essebsi.
Oct 27-28: Violence erupts in Sidi Bouzid after results of Tunisia's first free election are announced, in which the Islamist Ennahda party wins most seats in a constituent assembly.
June 11-12: Unrest triggered by an art exhibition of work deemed offensive to Islam. The government blames hardline Salafists and old regime loyalists.
