Mohammad Anwar Ishaqzai, governor of Zabul province says security forces ransacked some suspected areas but did not find the hostages.
Ishaqzai added that security agencies have been strictly working on the issue.
Conflicting reports have been published about number of the hostages, some state they were 30, some suggest 20 and some other then put it at 14 but Ishaqzai said that its specific number is still unknown.
They were driving in different vehicle when armed men stopped their vehicles on gun point in Nawrak area of Qalat, the provincial capital of Zabul, and kidnapped them.
No group has claimed responsibility for the abduction but the previous mass abduction was reportedly the work of Uzbek militants who have announced allegiance to Daesh.
