The Afghan intelligence agency foiled the bid by arresting a man, identified as Ghulam Nabi, who was digging a tunnel into the prison.
In a media statement issued here, the NDS said on Sunday that it has arrested Nabi, a resident of Herat City, who wanted to help the prisoners to escape through the secret tunnel that he dug a few kilometers.
In another operation, the intelligence agency arrested two money exchangers who were facilitating the transfer of cash between the insurgents.
They were identified as Mohammad and Abdul Ghani. The two were arrested from Shindand district of Herat province.
They had planned to transfer PKR 294,000 to Mullah Jamil, the Taliban’s shadow district chief for Shindand district.

The intelligence agency operatives have also secured release of two kidnapped residents of Faryab province.
