Three Afghan refugees who were executed by hanging in Iran on the charges of drug smuggling were buried in northeastern Takhar.

Executed last week, the Afghan suspects were imprisoned months ago in an Iranian jail, according to their family members and local officials.

"Without having any lawyer, my brother was awarded the death penalty in an Iranian court," said Juma Khan whose brother was among those executed. "This is an unfair decision and we want justice."

A mother of two, Shakira, who is now left alone to earn a living for her family demanded the government to stop execution of Afghans in Iran.

"My husband was deceived by the smugglers in Iran," Shakira said breaking into tears. "We want the government to prevent execution of ‎Afghans in that country."

According to the residents of Kelefgam district of Takhar, about 700 inhabitants of the district are being held in Iranian detention centers.

"We want the relevant authorities to free our citizens from Iranian jails," a resident Noor Ahmad said.

Unemployment is said to be one of the leading reasons that people flee Afghanistan, especially to Iran and European countries.

After Pakistan, Iran is considered the second largest home for Afghan refugees in the world.

So far, dozens of Afghans, most of them from Herat and Takhar provinces, have been executed by hanging in Iran.
