ZURICH, March 2 (AP)  What began as a routine training exercise almost ended in an embarrassing diplomatic incident after a company of Swiss soldiers got lost at night and marched into neighboring Liechtenstein.

According to the Swiss daily newspaper Blick, the 170 infantry soldiers wandered more than a mile across an unmarked border into the tiny principality early on Thursday before realizing their mistake and turning back.

A spokesman for the Swiss Army confirmed the story, but said it was unlikely that there would be any serious repercussions for Switzerland, well known for its neutrality.

“We’ve spoken to the authorities in Liechtenstein, and it’s not a problem,” the spokesman, Daniel Reist, said Friday.
