Hungary is defending a move to close off yet another border to prevent desperate migrants from crossing through on their way to Northern Europe. It has already divided opinion across Europe by building a fence along its border with Serbia, one of the main overland entry points into Europe's border-free Schengen zone. It is now looking to close off a second border with Croatia. Hungarian government spokesman Zoltan Zovacs says while the fence is ugly and undesirable there is no other option.
