Hungary would have to use force at its southern border with Serbia to protect the European Union’s frontier if Turkey delivers on a threat to open the gates for refugees through the Balkans towards Europe, Hungary’s Prime Minister Victor Orban said.

Orban said currently there were about 90,000 people on the Balkans migration route and their number could rise to 100,000 shortly.

If Turkey sets off further hundreds of thousands, then we will need to use force to protect the Hungarian border and the Serbian-Hungarian frontier, Orban said.

Orban warned that the current situation in Syria could soon have consequences for Hungary, whose borders are also EU borders.
