Thousands of refugees have crossed from Serbia into Croatia after being stranded in deteriorating conditions for days. The United Nations refugee agency estimates that 2,000 to 3,000 people were allowed to enter Croatia, which will likely increase the strain on neighboring Slovenia. The situation has worsened as Turkey insists it should not be expected to turn into a “concentration camp” for refugees, even if it tightens its borders. Turkey’s prime minister, Ahmet Davutoğlu, argues that his country should not be expected to house all migrants fleeing war and persecution. The crisis continues to escalate as 10,000 people remain stranded in Serbia and the conditions for refugees deteriorate.
