Turkish customs seized 1.5 tons of drugs in an anti-drug operation at the Greek border, the country's Trade Ministry said.
According to the ministry, guards found the hashish in a tractor-trailer transporting soybeans at the Ipsala border gate in the northwestern Edirne province.
Acting on a tip, the squads discovered the drugs in 152 sacks - 10 kilograms each - hidden among the sacks filled with soybeans, the ministry added.
It has been the largest ever drug bust that Turkey has made in a single operation at the border gates, Anadolu Agency reported.
The driver of the tractor-trailer and two others thought to be related to the incident were arrested.
