>> arwa damon on a bus now that began moving in hungary. hopefully these people are heading to austria right now. a remarkable image, arwa to see the bus finally going. what happens when they get to austria. or germany. how will they set up a life? they will have to go into the system. bearing in mine. austria, germany are overwhelmed with the numbers they have already been receiving. there is a whole asylum application process. put into temporary refugee shelters. and then, eventually, at some point in time, they will start being able to send the kids to school. the adults will begin learning german or whatever language it is in the nation that they end up in. they will get jobs. restore the dignity they lost throughout the journey.
