Swiss infantry soldiers numbering 170 accidentally marched into the neighboring country of Liechtenstein when they got lost at night during a routine training exercise. The soldiers had reached 2 kilometers across the border before they realized their mistake and turned back.

The story was confirmed by a Swiss army spokesman.

"We've spoken to the authorities in Liechtenstein, and it's not a problem," Daniel Reist told The Associated Press.

Interior Ministry spokesman Markus Amman said the soldiers were hardly noticed in Liechtenstein.

"It's not like they stormed over here with attack helicopters or something," he said.

Liechtenstein is a country with a rich, industrialized, free-enterprise economy that ranks it at par with its large European neighbors. It has around 34,000 residents and is a little smaller than Washington, D.C. in terms of area.
