Tunisia's president declares state of emergency

TUNIS — Tunisia's official news agency said Friday that Tunisian President Zine El Abidine Ben Ali has declared a state of emergency as riots escalated in his North African nation.
An AP Television News reporter heard gunfire in the center of the Tunisian capital late Friday, as well as the popping of tear gas pistols as police fired on protesters. Police have repeatedly fired on crowds during nearly a month of riots.
Protesters have been fueled by pent-up anger at high unemployment and at a leadership many see as controlling and corrupt.
