Thousands of desperate men, women and children are continuing their journeys through Europe after overrunning riot police at the Croatian border.
The country said 9,200 refugees and migrants had entered the country in two days, many having been prevented from entering neighbouring Hungary by a 3.5m-high razor-wire fence.
Some are now camped out for the night less than a mile into Croatia, while others are boarding buses and trains.
Many are heading for Slovenia - but police there have stopped a train carrying 150 refugees and say they will return them to Croatia.
Croatia has put its army on standby and said it will close the border if similar numbers continue to arrive.
"Croatia cannot receive any more people," the interior minister said.
Armed police initially contained some 2,000 people who had gathered at Tovarnik railway station after being told transport was available.
Children were in tears as they struggled to cope with the crush and, unable to maintain control, the guards eventually had to let hundreds of people through.
One man was seen passed out on the ground.
Some of those who broke the border are now boarding buses inside Croatia to continue their journey, but tensions are rising among men separated from their families as police prioritise the most vulnerable women and children.
"I don't want to be registered in Croatia. I want to be out of here as soon as possible," said Khalid Nasr from Damascus, Syria.
"I want to go to Germany and nothing will stop me."
Border guards were also forced to stand down in the Croatia town of Batina.
Croatia, which joined the EU in 2013, had previously said it would not halt the passage of refugees heading further into the bloc.
Many of those who entered Croatia are thought to be heading towards Slovenia - but on Thursday evening Slovenian police halted a train carrying 200 refugees at the Dobova train station.
Meanwhile MEPs have backed a European Union plan to distribute 120,000 refugees aimed at relieving pressure on Greece, Italy and Hungary.
The European Parliament met this morning for an emergency session to approve the proposal from the European Commission.
EU leaders will convene next Wednesday to try and agree a unified response to the biggest movement of people Europe has seen since the Second World War - a day after justice ministers meet to discuss new plans for dealing with the crisis.
Fine Gael Dublin MEP, Brian Hayes, says measures in the proposals passed today include additional resources to assist member states in processing applications and returning economic migrants.
Fine Gael MEP Sean Kelly says every European country must play their part:
Hungary's foreign minister said on Thursday that the European Union's refugee policy has failed and the bloc should look at others ways to support those in need.
