Ventimiglia: The new doorway to Europe
French President Nicolas Sarkozy is due to meet Italian Prime Minister Silvio Berlusconi to discuss tensions over migrants from North Africa.
Italy has angered France by granting visas to thousands of migrants, allowing them to travel across Europe's border-free Schengen zone.
About 25,000 migrants have arrived in southern Italy so far this year, many driven by the unrest in North Africa.
The BBC's Matthew Price reports on one group's journey, starting in the northern Italian town of Ventimiglia.
