A gang set fire overnight to a small synagogue, a Jewish leader said, in what appeared to be the first attack on a Jewish institution since the start of the unrest that forced the North African's nation's autocratic President Zine El Abidine Ben Ali to flee to Saudi Arabia.
The country's caretaker government has said about 78 people lost their lives in the unrest fueled by widespread corruption and repression, but that figure has been contested by the opposition.
Bakr N'diaye, the head of the mission sent by the U.N. High Commissioner for Human Rights to investigate the violence, said his team counted 147 deaths beside the 72 deaths in prison riots linked to the unrest.
The unrest has spread to Egypt, where protesters are calling for the departure of President Hosni Mubarak, as well as to Jordan and Yemen.
The interim government in Tunisia has been trying to stabilize the country, but scattered protests and unrest have continued. Police in the capital, Tunis, dispersed demonstrators Monday with tear gas and youths sacked several state offices in the central-western town of Kesserine.
A small synagogue in the southern town of El Hamma was set alight overnight and a Torah was burned, said Perez Trabelski, who head the Ghriba synagogue in Djerba. Gangs also damaged four cars belonging to Jews in Djerba, he said.
"They want us to leave and seed discord between the Jewish and Muslim communities who have long lived in harmony," Trabelsi said in a telephone interview.
Ghriba was the target of a deadly terror attack in 2002 that left 21 people dead, including 14 German tourists, in the only major attack in Tunisia by Islamist extremists.
Meanwhile, Tunisian authorities on Tuesday freed a former Guantanamo detainee as part of a promise by the interim government to free all political prisoners, according to attorney Samir Ben Amor.
Abdallah Hajji, 55, was sentenced to eight years in prison after his return in 2007 from the U.S. prison in Guantanamo Bay, Cuba. Another former Guantanamo detainee was released from a Tunisian prison in June.
The European Union said Monday it plans to impose an asset freeze on Ben Ali and his wife, and promised to help the country move toward full democracy. Tunisia has issued an international arrest warrant for Ben Ali, accusing him of taking money out of the country illegally.
