Concerns are being raised about how Europe is dealing with the refugee crisis.

The scale of the crisis was again highlighted today after at least 50 refugees, who are believed to have suffocated, were found in a Hungarian registered vehicle.

Authorities in Austria said it may be tomorrow before they know how many people perished in the lorry which was abandoned on a roadside.

A protest was held in Dublin by the Anti-War Movement tonight on the issue.

Anti-Austerity Alliance TD Ruth Coppinger said that refugees are being treated appallingly by Europeans on arrival.

"Tear gassing of human beings fleeing war trying to get into a country. Walls being built to keep people out and now we're finding families, I'd imagine that will be found, that have been suffocated," said Deputy Coppinger.

"Why is this happening? It's not happening because Europe is the destination that most refugees want to go to, in fact a fraction of people who are displaced come to Europe."

However speaking in Vienna, the EU Commission's Foreign Affairs chief Federica Mogherini said that it is up to European governments to jointly address the refugee crisis.

"If we act in time and consistently we can both save lives, and tackle criminal organisations, and prevent tragic losses," said Ms Mogherini.

"Here again I say, it is not for the Commission to make new proposals, it is for the Member States to take responsibility."
