Ghanbari said that the illegal haul was confiscated during an armed clash between the police and the smugglers on the main routes of the provincial capital, Zahedan.
“The cargo contains 1,640kg of opium, 27kg of hashish, and 7kg of crystal,” he added.
He went on to say that two AK47 rifles and ammunitions were confiscated from the drug-traffickers.
“Two offenders were arrested and handed to the judiciary,” Ghanbari concluded.
In relevant remarks on Sunday, Police chief of Yazd province Brigadier General Abbas Ali Behdani Fard said that 460 kilograms of narcotics have been seized in the Central province in a single operation.
Iran is in the forefront of the fight against drug trafficking and thousands of Iranian police forces have been so far martyred to protect the world from the danger of drugs.
The Iranian anti-narcotic police have always staged periodic operations against drug traffickers and dealers, but the latest reports - which among others indicate an improved and systematic dissemination of information - reveal that the world's most forefront and dedicated anti-narcotic force (as UN drug-campaign assessments put it) has embarked on a long-term countrywide plan to crack down on the drug trade since several years ago.
The Iranian police officials maintain that drug production in Afghanistan has undergone a 40-fold increase since the US-led invasion of the country in 2001.
Afghan and western officials blame Washington and NATO for the change, saying that allies have "overlooked" the drug problem since invading the country 19 years ago.
