Berkasovo, Serbia: Two Syrian sisters hold up a sign on an improvised board made of pink rubber - an attempt to keep fellow refugees calm as they wait in long, slow-moving queues at the Serbia-Croatia border.
"There are no buses right now. Be patient, we will tell you when to go," reads the message written in Arabic, carried by Rawan, 23, her 12-year-old sibling Dina and a Czech volunteer, as lines of people stretch back for hundreds of metres.
"While we're waiting to cross the border we're helping volunteers to explain to people what's going on," Rawan said.
"We have been here since 7:00 am this morning and I am dead tired after spending 48 hours in buses."
The sisters, travelling from war-torn Damascus with their father, were among around 2,000 refugees waiting to cross into Croatia from Serbia on Sunday afternoon as the flow of travellers allowed to go over the border dramatically slowed down.
Like tens of thousands before them, they are desperately trying to reach northern Europe, but their plans have been hindered by EU member Hungary's decision to close its Croatia border to migrants.
Since the razor wire was rolled out in the early hours of Saturday, the men, women and children on the move are being redirected to Slovenia after crossing into Croatia.
