Four Iranian nationals have been arrested by Afghan border police for attempting to smuggle drugs out of Afghanistan into Iran, local officials said Wednesday.
"The men wanted to carry 1200 kilograms of heroin to Iran which is when the border police captured them," border police commander Gul Nabi Ahmadzai told TOLOnews.
The police have started investigating the men, he said.
The four men were caught in western Herat province which borders with Iran.
