BELGRADE, Serbia, Ramadan 1, 1436, Jun 18, 2015, SPA -- Hungary's plans to build a fence along the border with Serbia to stop a flow of migrants reaching the country were met with criticism both in the Balkans and the European Union on Thursday, with the Serbian prime minister saying he was "shocked and surprised" by the project that could isolate his country. Aleksandar Vucic said "walls and fences" are not a solution for the crisis that has seen tens of thousands of migrants from the Middle East and Africa crossing the western Balkans, trying to reach the European Union as they flee wars and poverty in their home countries. Announcing the plans, Hungarian Foreign Minister Peter Szijjarto said Wednesday the 4-meter (13-foot) -high fence along the 175-kilometer (109-mile) southern border with Serbia wouldn't contravene any of Hungary's international legal obligations. --SPA 14:34 LOCAL TIME 11:34 GMT www.spa.gov.sa/w
