The 19-metre tunnel leading from Serbian territory to Hungary was discovered by a police patrol during a field search near the town of Ásotthalom, on Monday afternoon, a police spokeswoman said.

Earlier in the day the Hungarian authorities halted four groups of border violators, altogether 74 illegal immigrants in the region.

Police officers will hold an on-site inspection at the tunnel’s entry and guard it until it is buried.
