As several thousand more migrants arrived in Austria from Hungary via Croatia, Budapest abruptly decided to reopen a border crossing with Serbia whose closure on Tuesday had sparked a surge of migrants into Croatia.
The Horgos-Roszke 1 crossing is on the highway that before the migrant crisis engulfing Europe was the main route linking Belgrade and Budapest.
The closure added distance and uncertainty for those undertaking the gruelling journey across the Balkans into western Europe, with Croatia saying more than 25,000 had entered its territory in the past four days.
Within days of the border closure, Croatia said it could not cope with the influx of arrivals and began to redirect the migrants back towards Hungary or towards Slovenia, sparking angry reactions from both countries.
