Gunfire rings out near Tunisia opposition building

Gunfire has rung out in central Tunis near the Interior Ministry, as police and troops try to calm tensions after the president's ouster.
Issam Chebbi, a senior member of the main opposition party PDP, says a gunfight also broke out Sunday between security forces and unidentified attackers in front of the opposition party headquarters. A big crowd was gathered in front of the building and heavy security was deployed in the area.
Soon afterward, repeated volleys of gunfire were heard nearby, near the Interior Ministry. The source of the shots was unclear.
