"The police forces had focused their activities on a number of drug-smuggling gangs since a while ago, and during the last 24 hours they succeeded in disbanding 3 gangs trafficking over 3 tons of elicit drugs," Commander of Iran's southern province of Fars police forces Ali Mo'ayyedi told reporters this afternoon.
He noted that the police have seized 2,600 kg of opium, 500 kg of hashish, 120 kg of crack and 20kg of heroine.
The commander said the three bands worked through "a very complex" pattern of operation, and noted, "The disbanded groups operated regionally and trans-regionally and ran networks in several provinces, including Fars, Kohgilouyeh and Boyer Ahmad, Hormozgan, Khuzestan and Tehran.
The police commander further announced that the volume of drug seizure by the Iranian police has increased this year in comparison with the last year.
Iran lies on a transit corridor between opium producing Afghanistan and drug dealers in Europe.
The Islamic Republic has emerged as the leading country fighting drug trafficking after making 85 percent of the world's total opium seizures.
Since the 1979 Islamic Revolution, Iran has lost more than 3,300 of its security forces in its war against drug smuggling.
Over the past five years, it has contributed more than $50 million annually to Afghan anti-narcotics efforts.
