The attitude of a number of eastern European countries towards the migrant crisis facing the EU was "scandalous", French Foreign Minister Laurent Fabius said Sunday, pointing in particular to an anti-migrant barrier in Hungary.

"When I see a certain number of European countries, particularly in the east, who do not accept quotas (of migrants), I find it scandalous," he told Europe 1 radio.

He specifically pointed to a razor-wire barrier along Hungary's border with non-EU member Serbia, aimed at keeping out migrants, which Fabius said "did not respect Europe's common values".
