From the story here:
With France and Switzerland closing their borders to migrants since last year, the tens of thousands in Italy have nowhere to go. The EU came up with a plan to relocate around 160,000 asylum seekers stuck in Italy and Greece but so far only 12,000 have been resettled. Italy says it can no longer be expected to deal single-handedly with the vast number of asylum seekers, most of them economic migrants, streaming across the Mediterranean. ...
The Italian government has warned that after years of taking in hundreds of thousands of migrants, the country is now at breaking point.
