Tunisia imposes curfew in capital amid riots

TUNIS – Police and protesters clashed in the center of the Tunisian capital Wednesday, bringing unrest to the government's doorstep after nearly a month of deadly protests that pose the most serious challenge ever to the president's two decades of iron-fisted rule.
The government imposed a curfew overnight, a highly unusual move in this generally stable North African country where pledges by the president to subdue rioters and create jobs have done little to dissipate public fury over unemployment and corruption.
