The flow of migrants into Hungary has hit another record as Prime Minister Viktor Orban's government prepares an unprecedented border clampdown.

Police said 4,330 migrants were detained Saturday, over 700 more than the previous one-day mark. Hungary is rushing to complete a fence on its border with Serbia and starting Tuesday, new rules criminalizing illegal border crossings and speeding up decisions about asylum requests take effect.

Hungarian authorities hope the 4-meter (13-feet) high fence, more police at the border and tighter migration rules should deter migrants from trying to enter the country as they strive to reach Germany or other destinations in Western Europe.

At the least, authorities hope it will bring order to their mandatory registration system — which has crumbled as the number of migrants has grown.
