Austria summoned Hungary's ambassador on Wednesday after Budapest stopped accepting asylum seekers from other EU states, defying European authorities and potentially swelling the influx of migrants that Vienna must process, Reuters reported. Hungary's government refused to take any more migrants sent there under EU regulations as of Tuesday, demonstrating its frustration with proposals to spread asylum seekers around the continent more equally. Vienna has asked the European Commission to check if that action violates EU treaties, a foreign ministry spokesman said.
