Turkey ordered a cargo plane carrying arms from Iran to Syria to land at a Turkish airport on Wednesday, the Istanbul-based Dogan News Agency reported.
On the plane were allegedly weapons connected to Iran's nuclear program, Dogan reported. The plane landed in the city of Diyarbakir on Wednesday.
Turkey's foreign ministry denied Dogan's report, saying that it is standard procedure for Iranian cargo planes to request permission to fly over Turkey and sometimes be required to make unscheduled landings to be searched.
Security officials arrived at the airport to check the plane's contents, Turkish news agencies reported.
Turkey's official Anatolia news agency confirmed that the plane, heading from Tehran to Aleppo, Syria, was searched Wednesday. But Anatolia and the government did not say what the cargo plane was found to be carrying.
The report comes just one day after Israel seized a ship smuggling Iranian weapons to Gaza. Israel Defense Forces estimate that the cache found on the ship, which contains missiles with a range of 35 kilometers, could total 50 tons.
