"With regard to all those people who are politically chased out of their country we have to be able to welcome them. Every country has to respond to that. France, Germany, others have, but when I see certain countries that do not accept [migrant] quotas, I find that scandalous," Fabius told the French Europe 1 radio.
"In particular eastern European states. They are extremely harsh. Hungary is part of Europe, which has values and we do not respect those value by putting up fences," Fabius said, adding that Hungary was not respecting EU values.
On Saturday, Hungary completed construction of an anti-immigration fence on the country’s southern border with Serbia.
