The Tunisian prime minister has announced he will dissolve the government following the assassination of a top opposition leader.
Prime Minister Hamadi Jebali said he would form a new government of technocrats to guide the country to elections "as soon as possible."
The killing on February 6 of leftist leader Chokri Belaid sparked protests in Tunis and elsewhere including Sidi Bouzid, the birthplace of the Jasmine Revolution that toppled Zine el-Abidine ben Ali in January 2011.
Since the uprising, Tunisia's new leaders have faced many protests over economic hardship and political ideas.
Belaid had been critical of the moderate Islamist party, Ennahda, that dominates the government.
Ennahda leader Rached Ghannouchi denied any involvement by his party in the killing.
In Washington, the State Department condemned the assassination.
French President Francois Hollande also expressed concern over the killing.
