Turkey's foreign minister says the country's authorities have intercepted an arms shipment from Iran to Syria.
Ahmet Davutoglu confirmed Friday a report saying a truck containing weapons had been intercepted.
He says an investigation has been launched. He did not elaborate.
German daily Sueddeutsche Zeitung on Thursday cited "western diplomatic sources" as saying that Turkey had stopped a weapons delivery from Iran on its way to Syria which was believed to be destined for Lebanon's Hezbollah militia.
In March, Turkish authorities seized the cargo of an Iranian plane bound for Syria because the shipment violated U.N. sanctions. Turkish media said the aircraft was carrying light weapons, including automatic rifles, rocket launchers and mortars.
