More than 1000 refugees walk away from Hungarian train station, headed for Austria

More than 1000 migrants stranded for days at Budapest's main train station have reportedly left the building, intent on walking to the Austrian border.

The huge refugee crowd included people in wheelchairs and on crutches, as well as parents carrying children on their shoulders, all prepared to march 175 kilometres to the border.

"We are very happy that something is happening at last, The next stop is Austria. The children are very tired, Hungary is very bad, we have to go somehow," 23-year-old Osama from Syria told AFP.

The migrants were part of an estimated 2,000 people stuck in makeshift refugee camps at Keleti station, after railway authorities had blocked them from boarding trains to Austria and Germany because they lacked EU visas.

Police watched the silent migrants walk through the Hungarian capital but did not intervene, the AFP correspondent said, adding there was no sign of conflict at the moment.

The march was causing traffic jams on the main route into the city from the western Buda area.

It came as Hungarian lawmakers debated tough new anti-immigration measures on Friday afternoon, including criminalising illegal border crossing and vandalism to the new anti-immigrant razor-wire fence erected along the border with Serbia.
