An AFP correspondent reported that the group broke doors and windows of the Ennahda building and SET alight tyres on the town's main road.
A similar protest was under way in the town of Regueb, some 50 kilometres (30 miles) from Sidi Bouzid, said witnesses, where a gunshot was fired at the local Ennahda offices.
Ennahda emerged the largest party from the vote, taking 41.47 percent of votes and 90 seats in a new 217-member assembly that will rewrite the constitution, appoint a president and form a caretaker government.
But the ISIE electoral body said Thursday that six of the Petition for Justice and Development's candidates' lists, including in Sidi Bouzid, had been invalidated notably due to "financial irregularities".
The group is backed by Hechmi Haamdi, a rich London-based businessman said to have close ties to Ben Ali.
To the surprise of many observers it took fourth place in Sunday's elections, with 19 seats on the assembly. The grouping had been leading the vote count in Sidi Bouzid.
Haamdi had campaigned from London via his satellite television station al-Mustakilla.
It was on that station that he said earlier Thursday he "feared" his supporters would display anger after Ennahda refused to include his grouping in negotiations to form a new government.
