Violent protest in Tunisia

Rough Cut (No reporter narration)
Troops fire in the air to disperse a crowd attacking government offices in Sidi Bouzid.
It was here that 10 months ago vegetable seller Mohamed Bouazizi set fire to himself in a protest that ignited revolts around the Arab world.
Rachid Ghannouchi, the leader of Ennahda, the Islamist party which won Tunisia's first free election appealed for calm, accusing forces linked to the ousted president of fanning violence.
The unrest was not linked directly to the Ennahda win, but to the fact that a party headed by a businessman popular in the town had been eliminated from the ballot over allegations of campaign finance violations.
An Interior Ministry source said a night curfew would be imposed in the town from 7 p.m. (1800 GMT) until 5 a.m, with exceptions made for emergencies and health related issues.
