The Tunisian authorities and the country's main Islamist movement on Saturday denounced the murder of a Polish priest who was found dead in the country with his throat slit.

Marek Rybinski, 34, was found dead Friday in the garage of the private religious school in the Manouba region near the capital Tunis where he was responsible for the accounting.

Ousted Tunisian president Zine El Abidine Ben Ali suffered a stroke and was "in a coma" in a Saudi hospital, a family friend said Thursday, as more details of corruption under his rule came to light.

Nearly 1,000 Tunisian migrants arrived on the Italian island of Lampedusa overnight, where the government has already declared a humanitarian emergency, coast guards said Sunday.

Viewed from the ongoing pace of televised news, the tumult on Egypt's streets seems ready to engulf the entire Middle East. Indeed, only days after thousands of protestors filled downtown Cairo's main thoroughfare to demand an end to Hosni Mubarak's rule, Yemen's President Ali Abdullah Saleh announced he would be stepping down at the end of his term, and his son would not run for office, while Jordan's King Abdullah II fired his cabinet, appointed a new Prime Minister, and vowed political reform. Rumblings of protest also echoed in Algeria, Oman and Morocco.

Undoubtedly, the popular uprisings in Tunisia and Egypt have brought extraordinary change to Arab politics, challenging regimes to alter the way they govern, and providing new political freedoms for the people. But while many foreign investors have deemed the Middle East North Africa (MENA) region's new political uncertainty as a risk -- Moody's downgraded Egypt's credit ratings to Ba2 with a negative outlook, and other credit ratings agencies followed suit -- regional businesses and investors have taken a different approach. They believe that political changes that usher in more democratic governments in the region will pave the way for long-term stability and growth.

British Foreign Secretary William Hague voiced concern over possible conflict between Israel and Hizbullah following last month's collapse of the Lebanese government.

A wave of uprisings in Arab countries is a sign of an "Islamic awakening" which was envisaged when the 1979 Iranian revolution took place, Iran's supreme leader Ayatollah Ali Khamenei said on Friday.

"Today's events in North Africa, Egypt and Tunisia and some other countries have different meanings for us," Khamenei, the commander-in-chief and spiritual guide of Iran, said in a sermon at Tehran university during the Muslim weekly prayers.

Arsonists set fire to a synagogue in the southern Gabes region of Tunisia, a leader of the local Jewish community said Tuesday.

"Someone set fire to the synagogue on Monday night and the Torah scrolls were burned," Trabelsi Perez told Agence France Presse, criticizing the lack of action by the security services to stop the attack.

Europe's foreign ministers on Monday froze the assets of ousted Tunisian leader Zine El Abidine Ben Ali and his wife in response to a request from the Tunisian authorities.
