   Croatia says it will allow migrants to travel on to northern Europe, opening up a new route a day after Hungary sealed its border with Serbia. 
   
   More than 150 migrants have crossed into Croatia from Serbia, with some of those stranded on Serbia's border with Hungary making a similar trip. 
   
   At the Serbia-Hungary border, Hungarian riot police have fired tear gas at migrants who were trying to break through a border post. 
   
   Many migrants want to reach Germany. 
   
   New border restrictions and a row over allocating migrants have exposed bitter divisions in Europe over the crisis. 
   
   The clashes at the Serbia-Hungary border on Wednesday afternoon occurred after police sealed a key crossing point near the town of Roszke. It has been used by tens of thousands of migrants to enter the European Union's Schengen zone, which allows people to travel between countries without restrictions. 
   
   The BBC's James Reynolds, at the scene, reports that migrants stranded on the Serbian side chanted "Open open", and threw plastic water bottles at the police, who forced the crowd back by firing tear gas.

   The BBC's Lyse Doucet says buses, vans and cars have been taking migrants away from the Serbia-Hungary border area towards the Serbian capital, Belgrade, and the border with Croatia. 
   
   Hungary declared a state of emergency in the border area on Tuesday, with hundreds of army and police deployed to enforce new laws making it an offence to breach a razor-wire border fence. 
   
   The first trials of refugees detained for illegal border crossing have been held in the Hungarian city of Szeged. 
   
   Ahmed Suadi Talib, an Iraqi who was studying in Syria, was the first to be convicted under the new law, and was excluded from Hungary for one year. 
   
   Speaking through a translator, he told the court he had fled Syria to escape Islamic State. He entered Hungary via a hole in the border fence, he said, and did not know crossing into Hungary was illegal.

   The EU's border agency says more than 500,000 migrants have arrived at the EU's borders so far this year, compared with 280,000 in 2014. 
   
   Many are fleeing conflict and poverty in countries including Syria, where a civil war has been raging since 2011. 
   
   The migrants have been crossing from Turkey, with about 1,000 in the city of Edirne on Wednesday, waiting to organise a crossing into Greece. Their journey would then take them to Macedonia and Serbia. 
   
   Until Monday, most poured into Hungary and then crossed into Austria to reach Germany. Both Germany and Austria have introduced tighter border controls to control the flow. 
   
   Trains from the Austrian city of Salzburg to Germany have been halted, leading to a build-up of migrants at the city's station. Several hundred people have left the crowded station and are now walking towards Germany. 
   
   The UK is set to welcome the first Syrian refugees to be taken in under the government's expanded resettlement scheme "in the coming days, Home Secretary Theresa May has said. 
   
   The UK has pledged to take up to 20,000 refugees over the next five years. 
   
   At the scene: James Reynolds, BBC News, Serbia-Hungary border 
   
   Several hundred refugees and migrants are milling about here on the last few metres of Serbian territory. In front of them, the border gate into Hungary is locked. A line of Hungarian police wearing riot gear stands on the other side of a roll of razor wire. 
   
   "Open the gate, open the gate," chants a group of several dozen migrants and refugees. 
   
   One man half-scales the gate and begs the Hungarian police to let everyone in. But he gets no response. 
   
   Further back in the makeshift encampment, the atmosphere is much calmer. Volunteers distribute food and drink from vans. Next to a TV satellite truck, several people charge their smartphones. Refugee families rest in their tents. 
   
   "I will stay here forever," says Saleh, a law student from Damascus. "I can't go back."

   Dozens of refugees walked through fields into Croatia from the official Serbian border crossing at Sid. 
   
   Several told me they were hoping to reach Slovenia and the Schengen area. Others shouted "Thank you, Serbia" as they left. 
   
   Croatian police vans were waiting for the group as they crossed the border. All of them boarded without a struggle. 
   
   Croatia says it is ready to receive migrants or "direct" them to where they want to go. 
   
   Serbian media say at least 10 buses were heading to the town of Sid, near the Croatian border, from Presevo near Serbia's southern border with Macedonia. 
   
   One of those who arrived on Wednesday, Amadou from Mauritania, told AFP news agency: "We heard that Hungary was closed so the police told us we should come this way." 
   
   Croatia's Prime Minister Zoran Milanovic told parliament that authorities were "ready to receive or direct those people where they want to go. 
   
   "They will be able to pass through Croatia and we will help, we're getting ready for that possibility," he said. 
   
   Migrants have been crossing into Croatia on foot - avoiding the official border crossing point. Police are registering them before taking them to reception centres. 
   
   Croatian media have warned of the dangers posed by landmines dating back to Croatia's war of independence in the early 1990s, even though experts say the areas are clearly marked. 
   
   The Serbian minister in charge of the government's committee on migrants, Aleksandar Vulin, argued that the border closure by Hungary was unsustainable for his country.

   On Tuesday, Hungary declared a state of emergency in the border area, with hundreds of army and police deployed to enforce new laws making it an offence to breach a razor-wire border fence. 
   
   Police sealed a railway crossing point near Roszke which had been used by tens of thousands of migrants to enter the European border-free Schengen zone. 
   
   The move has all but stopped the inflow. On Wednesday, Hungarian police said they had detained 367 migrants entering illegally - and the first criminal proceedings have been launched.

   'We will help' 
   
   A group of about 40 migrants arrived in the border town of Sid in Serbia on Wednesday. They had travelled by bus from the Serbian town of Presevo near the Macedonian border in the south. 
   
   "We heard that Hungary was closed so the police told us we should come this way," Amadou, 35, from Mauritania told AFP news agency. 
   
   "We don't know what we should do now. Do we have to catch a boat?"

   Serbia worried 
   
   The Serbian minister in charge of the government's working committee on migrants, Aleksandar Vulin, argued that the closure of the border by Hungary was unsustainable for Serbia. 
   
   He told the BBC's Lyse Doucet that contact between Serbian and Hungarian officials had been minimal. 
   
   Analysis: BBC's Guy Delauney, Belgrade 
   
   All year, Serbia has taken a relaxed attitude towards the migrants and refugees entering from neighbouring Macedonia. 
   
   The authorities understood that few of the people coming in would want to stay, although some expressed regret that people desperately fleeing conflict did not view Serbia as a desirable destination. 
   
   But Hungary's fence and its criminalisation of unofficial border crossings has brought a halt to the flow of people across Serbia. 
   
   If an exit into Hungary becomes impossible, the number of refugees here may begin to rise, challenging not only the country's capacity for dealing with asylum seekers but its citizens' hitherto admirable tolerance and empathy. 
   
   Serbian alarm over stranded migrants 
   
   Hungary has also said it could extend its fence to the border with Romania - a possible new route. 
   
   Romania said this would violate the "European spirit" of co-operation.

   Image copyright AP Image caption Migrants are angry at the Hungarian decision which has all but stopped the flow ||||| HORGOS, Serbia — In one of the worst bursts of violence that this tense refugee summer has seen, Hungarian riot police responded on Wednesday to rocks, taunts and small fires set by agitated migrants at the border crossing here with water cannons, head-cracking batons and both tear gas and pepper spray. 
   
   Although the word was quickly spreading along the migrant trail that heading toward Croatia from Serbia was a better bet than trying to push through the heavily guarded border into Hungary, hundreds of straggling refugees continued to turn up at the crossing here in hopes that Hungary would change its mind and let them through. 
   
   But Hungary did not change its mind — prompting a grim demonstration of what can happen when an unstoppable force meets an immovable object. 
   
   And the demonstration is likely to continue as more migrants and refugees try to escape war and poverty in their homelands and find a new life in a continent that cannot agree on what to do with them. Already, the migrant trail was adapting, finding new ways to reach western Europe. ||||| Refugees blazed a new pathway through Europe on Wednesday, with hundreds hiking through cornfields to reach welcoming Croatia even as others faced tear gas and water cannons from Hungarian police determined to turn them away. 
   
   The contrasting scenes along the Serbian border highlighted both the make-or-break resolve of the asylum seekers and the growing friction facing Europe, which has failed to create a coordinated policy for the unprecedented influx of economic migrants and war refugees from the Middle East, Africa, Afghanistan and Pakistan. 
   
   “We hit a stone and we flow around it,” said Arazak Dubal, 28, a computer programmer from Damascus, who had been on the road for 18 days. 
   
   He and his three companions reached Belgrade only to discover on Facebook and WhatsApp that the Hungarian border was closed to refugees. 
   
   “So I went to Google Maps, and here we are,” said Dubal, huffing in the hot afternoon as he trudged across the farm fields. 
   
   
   
   
   
   A two-hour drive to the northeast — along Serbia’s frontier with Hungary — the route was slammed shut. 
   
   Just steps from Hungary, thousands of people spent the night in the wet grass on the Serbian side of the border. Hours later, hundreds tried to punch through the cordon of razor wire and riot police massed near the Serbian border town of Horgos. 
   
   But they ran headlong into security forces­ who unleashed tear gas and pepper spray to drive them back. Some refugees were swatted by batons and crumpled to the ground in pain. 
   
   [New threat on the refu­gee trail: land mines] 
   
   “Open the door!” the refugees yelled as they hurled water bottles and debris at riot police. 
   
   Nearby, children screamed for their missing parents. Water cannons sprayed crowds on the Serbian side, forcing refugees to retreat to a squalid squatters’ camp that took root just after Hungary closed the border Tuesday. 
   
   There were no major injuries, but some refugees were treated by Serbian authorities for respiratory problems from the tear gas and at least one migrant had a leg injury, the Associated Press reported. 
   
   It was the first major clash between security forces­ and migrants since police used stun grenades to stop refugees from crossing into Macedonia from Greece almost a month ago. 
   
   “We fled wars and violence and did not expect such brutality and inhumane treatment in Europe,” said Amir Hassan, who was drenched from a water cannon and tried to wash tear gas from his eyes, according to AP. 
   
   “Shame on you Hungarians!” he shouted, pointing toward the Hungarian police. 
   
   At the United Nations, Secretary General Ban Ki-moon called Hungary’s border crackdowns “unacceptable.” 
   
   “All the countries have their domestic problems,” he said, “but since they are the people fleeing the wars and persecutions, then we must show our compassionate leadership.” 
   
   Neighboring countries continued to heap scorn on Hungary’s decision to blocks its southern border. 
   
   “Barbed wire in Europe in the 21st century is not an answer, it’s a threat,” complained Croatia’s prime minister, Zoran Milanovic, in a direct jab at the blockades by neighboring Hungary. 
   
   Milanovic promised that refugees would be allowed to pass through his country. 
   
   He told lawmakers in Zagreb that Croatia would “accept and direct” the migrants to transit the country — comments that rocketed through the social media networks used by the refugees and increased the march toward Croatia. 
   
   [ The limbo of the no man’s land ] 
   
   The river of migrants was swelling by the hour. 
   
   By late afternoon, more than 600 migrants walked through fields and along small roads to cross from Serbia into Croatia, a European Union member, where officials set up posts to register names and details. 
   
   Many traveled by bus from Macedonia and Hungary; others pulled up in taxis before crossing the border on foot and receiving a polite reception from authorities. 
   
   “We want to keep them moving as quickly as possible,” said Zdravko Helic, a civil protection officer in Tovarnik. 
   
   He was proud to add, “We haven’t had a single incident.” 
   
   Saeed, 19, a student from Damascus, called Hungary’s treatment of the refugees “old-fashioned racism.” 
   
   “We’re the first today,” said Dubal, the Syrian refugee. “There’ll be thousands tomorrow.” 
   
   Afterward they were taken by bus to a refugee processing camp outside the capital, Zagreb, where they would be officially registered. 
   
   What happens after Zagreb was uncertain. 
   
   Croatian officials said they would probably allow the migrants to continue their journeys by bus and train to Slovenia, Austria, Germany and beyond. But it was only Croatia’s first day at the leading edge of the mass migration, and authorities were scrambling to coordinate their response with E.U. partners. 
   
   “We will walk all the way to Germany if we have to,” said Mohammad, 28, who worked in a mobile phone store in Aleppo, Syria’s largest city. 
   
   “Shop is gone, house is gone, some of family is gone,” he said. “So I will walk.” 
   
   Like many in the migrant stream, he declined to give his last name out of fear of reprisals against relatives back home. 
   
   The refugees had nothing good to say about Hungary. “Not nice at all,” said Abdullah, 24, from Aleppo, who smiled and waved at the Croatian police before they hustled him into a van. 
   
   “See? Very good service,” he joked.

   Read The Post’s coverage on the global surge in migration ||||| Egyptian billionaire Naguib Sawiris said he has identified two Greek islands that could be used to host Syrian refugees, and suggested setting up a joint-stock company to deal with the expected donations. 
   
   Sawiris, the chairman of Orascom Telecom Media and Technology Holding, has been in contact with the owners of the islands in hopes of moving ahead with the plan, according to a statement from his media office posted on his Facebook page late Monday. Sawiris said the talks would depend on whether the owners can secure approval from the Greek government. 
   
   The Egyptian billionaire had announced that he was interested in buying an island where refugees could be housed until they can return to their own country. In a Sept. 8 Bloomberg TV interview, Sawiris said the proposal was something motivated by a desire “to clear my conscience as a human being, and nothing more.” 
   
   The best way to deal with donations would be to set up a joint-stock company with a capital of $100 million, Sawiris said in his Facebook statement. Such a step would ensure that any money invested “will not be completely lost, as the asset (the island) will remain.”
target: – More than 500 migrants have been detained for illegally entering Hungary or breaching a border fence, with nearly 50 criminal cases on the books since new laws took effect yesterday, the New York Times reports, while the BBC notes that Hungarian riot police today fired tear gas at migrants trying to break through the border with Serbia. And as restrictions tighten, migrants are seeking other ways into Western Europe through Slovenia and Croatia, as well as through Hungary's border with Romania. Issues remain: Hungary’s poorer neighbors may be ill-equipped to handle the flow, and there are areas peppered with land mines, remnants of the Balkan Wars. While solutions are sought, thousands spent last night in a Vienna train station, per the Times, while at least 22 migrants drowned yesterday in the Aegean Sea, the Post notes—a sad repeat of a similar incident a couple of days earlier. Leaders of neighboring nations are scrambling to come up with their own plans for dealing with the influx, which is no small task: The EU border agency notes a head count of 500,000 migrants at EU nations' entry points so far in 2015; last year that number was around 280,000, the BBC reports. Many are refugees fleeing high-conflict areas such as Syria and Iraq, per the Washington Post, which adds there's a noted "absence of a coordinated policy for the unprecedented influx." "Barbed wire in Europe in the 21st century is not an answer, it's a threat," Croatia's PM says, per the Post, adding that Croatia would "accept and direct" migrants through his country. An Egyptian billionaire who says he wants "to clear my conscience as a human being" has come up with an even more creative stopgap for the Syrian refugees involved: hosting them on two available Greek islands, using a joint-stock company to accept donations, Bloomberg reports.
