A security sniffer dog reportedly found two Hellfire missiles headed for Portland, Oregon.
The dog reportedly discovered the missiles on March 12, after they arrived in Belgrade, Serbia on an Air Serbia passenger flight originating in Beirut.
Serbian media outlets reported that travel documents indicate the missiles were destined for Portland, according to the Associated Press.
Lebanese security officials said the two Oregon-bound missiles did not contain explosives and were exclusively for military training purposes.
The Hellfire AGM-114 missiles are lethal, U.S.-designed weapons that can be fired from land, sea or air against a range of targets. The missile was originally intended to be fired from a helicopter, and most versions use lasers to locate their targets.
The FBI is in Oregon investigating the attempted shipment of military-grade weapons to Portland.
“We don’t have any information on that yet,” Jennifer Adams, an FBI spokesperson, said on March 13, according to the AP.
Air Serbia is reportedly assisting in the investigation into how the missiles were transported aboard its passenger plane.
“[S]ecurity and safety are the main priorities for Air Serbia,” the airline said in a statement.
Scott Winegar, director of Homeland Security Education at Concordia University, called on the U.S. Defense Department to initiate investigations into the missiles.
“The other organizations that we have in the U.S. are not responsible for distributing Hellfire missiles," Winegar told KOIN. "That’s a Department of Defense asset so, wherever it came from, it would have to have come through the Department of Defense’s logistical chain. If it came from the U.S., if it came from our allies, that’s going to muddy the waters."
Hellfire missiles are reportedly commonly used in drone warfare by the U.S. armed forces.
While the U.S. has sold Hellfire missiles to several countries in the Middle East, including Lebanon, U.S. officials said the missiles should not have been on the Air Serbia plane, reports Inquisitr.
Robert Caruso, a former State Department and Pentagon employee, expressed uncertainty as to how the missiles came to be on the passenger flight.
“No -- there are Syrian-related things ongoing in Bulgaria but even that can’t answer this," he said, according to Inquisitr. "Probably stolen."
