BONNERS FERRY, Idaho -

For the ninth time this school year, a bomb threat has forced the closure of a school in Boundary County.

In the incident, confirmed Monday afternoon by the district superintendent, an unspecific bomb threat was called in; because it did not specify which school was involved, all five schools in the district were closed down as a precaution.

This was the ninth time a bomb threat has been reported in the district so far this school year.
