How is Tunisia one month after revolution?

As the unrest gathers momentum in the Middle East and Africa, Tunisia, the country where it all began, is still facing huge challenges.

President Ben Ali has fled to Saudi Arabia after losing power a month ago.

Tunisia now has an interim government which is preparing the country for national elections.

That government is now seeking to put Mr Ben Ali on trial on charges linked to the deaths of protesters during the uprising against his rule.
