KENAI -- A suspicious package was mailed to the Kenai Peninsula Borough courthouse.

The Peninsula Clarion said after the package was opened Monday afternoon by courthouse employees, the Kenai Fire Department was called immediately.

Alaska State Trooper spokeswoman Megan Peters said courthouse employees are not expected to return to the building until the contents of the package have been identified.

Alaska Department of Homeland Security and Emergency Preparedness spokesperson Jeremy Zidek said the state department has been told it is a "white-powder incident."
