Tunisian police fired tear gas Friday at demonstrators protesting what they view as a slow pace of government reforms.

Some of the protesters in the capital Tunis demanded the resignations of interim government leaders.

Tunisians have kept up calls for reforms since the uprising that led to the January ouster of former leader Zine al-Abidine Ben Ali.

The head of a national commission probing the unrest and violence in the lead-up to the revolution said Friday that his group has received almost 2,000 cases, including more than 200 for alleged homicides.

The fact-finding commission forwards its cases to Tunisia's judiciary system.

Tunisia's unrest sparked what is known as the Arab Spring, which led to citizens calling for reforms in Egypt, Syria, Bahrain, Yemen, Jordan and Libya.
