0555 GMT: Let's see. In Tunisia, where President Ben Ali was deposed more than a week ago, there are still protests every day. Indeed, on Friday the rally of thousands was the largest since the overthrow of the regime, and on Saturday about 400 police --- who days earlier had been facing down demonstrators --- were leading the march.
In Algeria, the security forces were successful in blunting a mass protest with checkpoints and batons, but at least 300 people still took the risk of gathering outside the headquarters of the opposition Rally for Culture and Democracy, providing dramatic photographs and video.
And Yemen, which normally only draws international attention over "Al Qa'eda" and US drone strikes, was noticed yesterday. About 2500 protesters, led by students and activists, tathered in Sanaa to demand the resignation of President Ali Abdullah Saleh. Comparing him to Tunisia's fallen leader, they shouted, ""Get out get out, Ali. Join your friend Ben Ali."
The protest was met by about 1500 security forces. A smaller demonstration supported President Saleh.
