Row escalates in blame game over exodus that has shaken EU

After suddenly landing in the path of the biggest migration in Europe for decades, Croatia said it could no longer offer them refuge and would wave them onwards, challenging the EU to find a policy to receive them.

Amid chaotic scenes at its border with Serbia, Croatia said it could not cope with a flood of refugees seeking a new route into the EU after Hungary kept them out by erecting a fence and using tear gas and water cannon against them.
