A number of the drug traffickers were also arrested and one of them was killed.
Iran has been engaged in a decades-long war on drugs which has cost the country many lives and huge amounts of money.
The UN has said in a report that drug trafficking represents a major challenge for the Islamic Republic of Iran.
According to the report, the geographical location of Iran, particularly its 923 km-long Eastern border with Afghanistan- the world’s largest opium producer-and Pakistan, has turned it into a major transit country for drugs.
In response to this challenge, the country has built one of the strongest counter-narcotics enforcement capabilities in the region over the years.
The UN also said Iran accounts for a huge percentage of the world’s opium, heroin and morphine seizures.
