Battle happening outside presidential palace in Tunisia

TUNIS, Tunisia (AP) - A gun battle is under way around the presidential palace in Tunisia as the army and police struggle to restore calm in the country.

Two residents say presidential guards loyal to deposed President Zine El Abidine Ben Ali are involved in Sunday's shootout in Carthage on the Mediterranean shore, about 15 kilometers (10 miles) north of the capital, Tunis.

The shooting broke out in the afternoon and is continuing, with sporadic but heavy gunfire. Carthage residents have barricaded themselves inside their homes amid the shooting.

Tunisian authorities have arrested the top presidential security chief and are trying to stop gunfights that erupted across the capital.
