Timeline of Tunisia violence: 2010-2015
Tunisia, the country that sparked the Arab Spring, has seen an uptick in deadly attacks since the 2011 uprising
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 killed about 60 police and military personnel since 2010.
A timeline of unrest:
17 December: 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.
14 January: Under massive popular pressure Ben Ali flees to Saudi Arabia.
25 February: 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.
27-28 October: Violence erupts in Sidi Bouzid after results of Tunisia's first free election are announced, in which the Muslim Brotherhood-linked Ennahda party wins most seats in a constituent assembly.
11-12 June: Unrest triggered by an art exhibition of work deemed offensive to Islam. The government blames hardline Salafists and old regime loyalists.
14 September: Four attackers killed in clashes at the US embassy amid protests over an anti-Islam film.
27 November – 1 December: 300 hurt in clashes between police and protesters in Siliana, southwest of Tunis.
6 February: Prominent opposition leader Chokri Belaid assasinated, triggering deadly protests and a political crisis that brings down the Prime Minister Hamadi Jebali. On 25 July, opposition leader Mohamed Brahmi is shot dead. In December 2014 claim both killings.
29 July: Eight soldiers are killed in the Mount Chaambi area near Algeria where Tunisian forces have been hunting an al-Qaeda-linked group since December. On 2 August, the army announces a major operation against what it dubs Islamist militants in the area.

18 March: Seventeen tourists from Poland, Italy, Germany and Spain are among 21 people killed as gunmen attack a Tunis museum, according to the country's prime minister.
