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 arrived after more than 10 years in exile in France.

He received a raptuous welcome.
