Tauhidi recalled that the vast majority of members of Daesh are former Taliban militants who "changed their position, but who continue to destroy, destabilize… and kill civilians."
According to Tauhidi, the fear is that Daesh may get financial and personnel support from Central Asian countries, which could be captured by the militants.
"This worst-case scenario may see the transformation of Afghanistan into a transit route for the smuggling of arms, minerals and people from the Middle East to Central Asia," Tauhid said.
In this connection, he pointed the finger at Pakistan, which he said maintains contact with the Taliban and Daesh, directing their actions in Afghanistan.
Separately, Tauhidi heaped praise on Russia's efforts to combat Daesh militants.
"In Syria, Russia proved that it is up in arms against terrorism. Russia's borders adjacent to Central Asia are currently under threat of a terrorist invasion. This is a big headache for Moscow," Tauhidi said.
Meanwhile, The Times reported late last week that Daesh had captured four districts in eastern Afghanistan, with 1,600 local militants pledging their allegiance to the terrorist group.
