serbian haven't been saying much. there are not be arabic language translators here. most of them speak arabic. they don't know if this border is going b to open tomorrow, for how long, will people who are syrian be given preferential treatment will, families be getting preferential treatment? what we know now is that the border the closed. it's expected to reopen tomorrow. and there is a funnel effect here. what has been for weeks and months an enormous river of migrants flowing all of the way from the middle east into europe has been reduced to one passageway in this gate, a passageway that is three shoulder widths wide and that is the only route left, legal route left into hungary. it is expected in the coming days and weeks from now there will be very large crowds gathered here trying to get in to hungary and then deeper into europe. lawrence? >> richard engel, thanks. chris hayes is up next.
