BUDAPEST, Hungary — The Hungarian government is considering building a 4-meter-high (13-foot-high) fence along the border with Serbia to stop the flow of migrants reaching the country, the foreign minister said Wednesday.

The government has asked Interior Minister Sandor Pinter to present preparations for the plan by next Wednesday.

“The pressure of migration which presents serious difficulties for Europe affects Hungary the most among EU member countries,” Foreign Minister Peter Szijjarto said. “Hungary cannot allow itself to wait any longer. Naturally, we hope there will be a joint European solution.”

Szijjarto said the fence along the 175-kilometer (109-mile) southern border with Serbia wouldn’t contravene any of Hungary’s international legal obligations. He said that the governments of Hungary and Serbia would hold a summit on July 1, when “we will inform our Serb friends … in detail of the Hungarian measures.
