TUNIS, Tunisia — Major gunbattles erupted outside the palace of Tunisia's deposed president, in the center of the capital, in front of the main opposition party headquarters and elsewhere Sunday as authorities struggled to restore order and the world waited to see if the North African nation would continue its first steps away from autocratic rule.
Police arrested dozens of people, including the top presidential security chief, as tensions appeared to mount between Tunisians buoyant over Zine El Abidine Ben Ali's departure and loyalists in danger of losing major perks.
There were cheers and smiles in much of Tunis as residents tore down the massive portraits of Ben Ali.
Prime Minister Mohamed Ghannouchi said on state TV that a new national unity government will "most certainly" be announced today "to open a new page in the history of Tunisia."
There are three legal opposition parties that could be included in the government Ghannouchi has been directed to form by the interim president, Fouad Mebazaa. Negotiations are advanced, Ghannouchi said Sunday night.
Worries among Tunisians, however, grew with the violence and worsening shortages of essentials such as milk, bread and fresh fish. "We're starting to feel it now," said Imed Jaound at the Tunis port, which has been closed since Friday, when Ben Ali fled to Saudi Arabia.
A gunbattle broke out around the presidential palace late Sunday afternoon in Carthage on the Mediterranean shore, about 10 miles north of Tunis. The army and members of the newly appointed presidential guard fought off attacks from militias loyal to Ben Ali, said a member of the new presidential guard. Helicopters were surveying the zone.
Residents of Carthage — a center of power in ancient times but now a Tunis suburb popular with tourists — said they have barricaded themselves inside their homes amid the shooting. Many soldiers surrounded the palace, but it was unclear whether any of the interim government's leaders were inside.
Other gunfights broke out near the PDP opposition party headquarters and a two-hour-long gunbattle raged behind the Interior Ministry, long feared during Ben Ali's reign as a torture site.
The security chief, Ali Seriati, and his deputy were charged with a plot against state security, aggressive acts and for "provoking disorder, murder and pillaging," the TAP state news agency reported.
Police stopped vehicles as the city remained under a state of emergency.
Hundreds of stranded tourists were still being evacuated from the country Sunday. The U.S. State Department issued a travel warning suggesting that U.S. citizens forgo travel to Tunisia and consider leaving if already there. It authorized the departure of nonessential U.S. Embassy personnel and of all family members of U.S. staff at government expense.
