Al-Jazeera Video: Exiled opposition leader returns to Tunisa

"Tunisia's so-called unity government is barely a day old and already four members from the opposition have quit, undermining its legitimacy.

Police clashed with protesters for another day in the capital, Tunis.

And there were emotional scenes at the airport, where opposition leader Moncef Marzouki [I have posted some of his articles (in Arabic)] arrived after more than 10 years in exile in France."
