(Reuters) - Emergency officials were investigating two envelopes containing white powder and marked "anthrax" found in Portland, Oregon, on Wednesday, one at a downtown Hilton hotel and the other at an airport.
Preliminary tests on the envelope from the Portland International Airport found nothing dangerous, according to fire department spokesman Paul Corah. Airport offices were evacuated, but operations at the airport were not disrupted, he said.
Results of tests on the envelope found at the Hilton are expected later Wednesday evening. Offices at the Hilton were evacuated, but not the hotel.
Earlier in the week, a similar envelope was found in offices of Portland's Lloyd Center shopping mall. That envelope was found to contain benign material. Corah said he did not know if the incidents were related.
He said he did not know if the letters were sent through the U.S. Mail.
