The FBI is investigating after suspicious packages were found at Minneapolis-St. Paul International Airport, according to reports.
WCCO says they were discovered Tuesday night by UPS workers in their cargo facility.
According to KSTP, they were addressed to government entities.
FOX 9 says they've been sent to the Minnesota Department of Health for testing.
What is in the packages, or what about them concerned the workers and officials, isn't clear.
This past weekend, part of the ticketing area in Terminal 1 was evacuated for more than an hour after an unattended bag was found. Initial tests on the bag came back positive for explosives.
However, officials later said the bomb squad found nothing inside except personal effects, and they aren’t sure what caused the preliminary test to come back positive.
