BEIRUT -- The Lebanese army said two

from Lebanon to Serbia and bound for Portland were used for training and did not contain any explosives.

Monday's announcement came after Serbia's authorities began investigating reports that a cargo package containing two missiles with explosive warheads was found on the flight.

The army said the missiles were being sent to the American company that produced them. It said the return was in accordance "with administrative and legal measures after the training ended."

On Sunday, Serbia's N1 television said the package with two guided armor-piercing missiles was discovered Saturday by a sniffer dog after an Air Serbia flight landed at Belgrade airport.

Serbian media said documents listed the final destination for the AGM-114 Hellfire missiles as Portland.
