While the U.S. debates whether to strengthen security at the U.S.-Mexico border, an official in Hungary said Thursday the country is prepared to create a third wall if necessary to control the flow of migrants from the Middle East.

If Slovenia and Austria were to refuse entry to migrants, the Hungarian government believes people would instead travel through Romania to get to Hungary. In order to protect its national interests, the government would increase defenses on its border with Romania to include another security wall.
