Hungary's prime minister says his government's plan to build a 4-meter (13-foot) high fence on the border with Serbia to stop the flow of migrants will also protect Europe "from every illegal entry."

Viktor Orban said Friday that "if a question is complicated, choose the easiest solution," so in the case of the migrants, "the state will defend its external borders."

Hungary has received more than 53,000 asylum requests this year, compared with fewer than 43,000 in 2014 and 2,150 in 2012.

Orban, in the Slovak capital of Bratislava to meet with Central European leaders and French President Francois Hollande, said Hungary considered it a state obligation to defend its borders and would not seek help for the task.

Serbia is opposed to the fence.
