The local officials confirmed that the suspects have been arrested by the security forces in Pashtun Zarghoon district.
Provincial Police Chief Gen. Aminullah Amar Khel confirmed the arrest of the individuals and said the detained suspects were also involved in the murder of two policemen.
He said the individuals had recently trained some residents of Herat and some other provinces including Ghor and Badghis for future terrorist attacks.
The anti-government armed militant groups including Taliban militants have not commented in this regard so far.
Herat is among the relatively calm provinces in West of Afghanistan but the security situation in some remote districts of Herat has deteriorated during the recent years.
The Taliban militants are active in some remote districts of Herat and often attempt to carry out terrorist related activities.
