Orban built a steel fence on Hungary’s border with Serbia to seal off the Balkans route of migration, where hundreds of thousands of people marched through from the Middle East to Western Europe at the peak of the crisis in 2015.

‘If Turkey sets off further hundreds of thousands (on top of those it has already), then we will need to use force to protect the Hungarian border and the Serbian-Hungarian frontier and I do not wish for anyone that we should need to resort to that,’ Orban said Wednesday night.

President Recep Tayyip Erdogan last week threatened to ‘open the gates’ to allow Syrian refugees to pour into Europe if the EU chose to criticise his invasion.
