The Latest: Hungarian PM says migrant crisis not resolved

Hungary's anti-immigrant prime minister says the emergency shipment of thousands of migrants to Austria doesn't solve his country's growing challenge of managing foreigners trying to travel through its territory.

Viktor Orban, whose nationalist government is seeking to seal its southern border with Serbia to block the path of asylum-seekers, told journalists that Saturday's mass mobilization of buses to transport Arab and Asian migrants west to Austria was an exceptional measure that would not be repeated.

He says the migrants' snarling of traffic on the country's major motorway and decision to camp beside it Friday night posed too grave of a safety risk for migrants and Hungarian motorists.

"It is unacceptable for them to paralyze traffic on the highway and they are putting their own lives at risk," Orban said of Friday's thousands of marchers from Budapest. Buses collected them from the roadside overnight and delivered them more than 150 kilometers (90 miles) west to the Austrian border by dawn.

Orban was speaking at his ruling party's annual picnic near Lake Balaton southwest of Budapest.
