Two Hellfire missiles found Saturday on a passenger flight from Lebanon to Serbia did not contain explosives and were only used for training, the Lebanese Army said in a statement to the National News Agency on Monday.

“They belonged to the Lebanese army, which decided to send them back to the American company that manufactured them upon agreement with it, in accordance with legal and administrative procedures and after training with them had been completed,” the statement said, according to Reuters.

Earlier it was reported by Serbian media that documents listed the final destination of the pair of AGM-114 Hellfire missiles as Portland, Oregon.

However officials there said reports they were coming to Portland were incorrect.

“Experts are determining whether the missiles were equipped with live or training warheads…,” a source at the Serbian prosecutor’s office told Reuters. “They were packed in proper transportation crates and supplied with paperwork.”
