Tensions are rising on the Bosnian-Croatian border, where scores of migrants are demanding entry to the European Union, amid reports this week of fresh police clashes, plummeting temperatures and inadequate living conditions.
Thousands of migrants and refugees fleeing wars and poverty in North Africa and Asia are sleeping rough near the border, which they hope to cross to gain access to the EU.
Several people were injured on Wednesday in clashes with Croatian police, with migrants accusing officers of beating them and smashing their phones.
Meanwhile, Doctors Without Borders warned that “as temperatures drop the situation becomes more difficult and tensions are rising.”
