Some of the Afghan migrants have accused the Iranian forces, border guards, of throwing 57 people into a river which resulting in to the killing of at least 23 of them, it has been reported.
Certain of the survivors of the incident have claimed that the Iranian border guards initially arrested the migrants from a bordering region and later threw them in to Harirod River.
According to reports, the incident took place earlier last week as the migrants were on their way to Iran, apparently for work opportunities.
The local officials in Herat have not commented regarding the involvement of the Iranian border guards in the incident but confirm that the public health authorities have received the dead bodies of several people who had apparently drowned.
Meanwhile, the acting minister of foreign affairs Mohammad Haneef Atmar has reportedly appointed a delegation to thoroughly investigate the incident.
This is not the first reports emerge regarding the alleged torture and killing of Afghan migrants by the Iranian border guards but numerous such incidents have been reported during the past several years.
