Not Out of the Woods Yet

The BBC reports from Tunisia, where the government has lost a dictator but hasn't lost all its dictatorial habits:

Security forces in the Tunisian capital have fired tear gas to try to disperse hundreds of demonstrators outside the interior ministry.

Police and masked men in civilian clothes, armed with sticks, moved through streets looking for protesters.

The renewed protest comes a day after police cleared huge crowds from the streets demanding the resignation of the interim prime minister…police fired tear gas and warning shots to disperse demonstrators.

Elsewhere in the Arab world, the wave of protests has hit Oman and Mauritania.

Update: Tunisia's interim PM steps down.
