Hungarian police say they have discovered at least 16 tunnels used by people traffickers to smuggle migrants across the border from neighbouring Serbia.
The small tunnels, which are around a hundred feet long, are located near the village of Csikeria and the town of Morahalom.
The discovery of the tunnels is said to have occurred after police managed to capture 26 illegal migrants from Afghanistan and Syria near the border.
According to a report from Italian newspaper Il Giornale, the people traffickers charge migrants as much as €3,500 to get into Hungary, and therefore into the European Union.
The tunnels have become the favoured way of sneaking into Hungary as the nation’s border fence has drastically reduced the number of migrants entering the country since it was built in late 2015.
