NICKELSDORF, AUSTRIA - SEPTEMBER 05: Migrants wait for buses to take them onwards into Austria after they crossed the border from Hungary into Austria on September 5, 2015 near Nickelsdorf, Austria. Last night the Hungarian government ordered a fleet of buses to take migrants who had been stranded by the cancellation of international trains at the main Keleti Railway Station and also to collect migrants that had began a walk from Budapest yesterday along the M1 motorway to Austria.
