Travellers try to board a train to Austria at the railway station in Budapest
Travellers try to board a train to Austria at the railway station in Budapest, Hungary, August 31, 2015. Austrian authorities toughened controls along the country's eastern borders on Monday, stopping hundreds of refugees and arresting five traffickers in a clampdown that followed last week's gruesome discovery of 71 dead migrants in a truck.
