Iran: Intercepted Arms in Nigeria were a 'Misunderstanding'

Iran is claiming there was a “misunderstanding” when its arms, mislabeled as “building supplies,” were seized last month at a Nigerian port.
Iranian Foreign Minister Manouchehr Mottaki told reporters Monday that the issue of the arms shipment, intercepted by Nigerian authorities last month at a Lagos port, had been addressed.
The artillery rockets and other ordnance were packed into shipping containers labeled as building supplies. “I think the misunderstandings have been settled in this field,” Mottaki told the Iranian state news agency IRNA. He added that the Iranian ambassador to Nigeria, Hussein Abdullahi, had been replaced, but did not specifically say the move was connected to the arms incident.
According to the Associated Press, there were concerns that the arms were headed for Nigerian politicians who intended to respond with violence if they lost in upcoming elections.
Arms supplies are quite frequently "mislabeled" as building supplies.  Happens all the time.  Doesn't it?
