"I do not think that there is such a risk. Such incidents happened before and took place without long-term consequences," Kabulov told Sputnik.
On Sunday, Iranian media reported that one Iranian border guard had been killed and two others injured in an armed clash with Taliban* forces near the village of Sasouli in Iran's southeastern province of Sistan and Balouchestan.
The Taliban forces also suffered casualties as a result of the clash in Sasouli, but the extent was unclear, the Tasnim news agency reported, citing the Iranian Border Police Command.
This was the second deadly clash on the Iranian-Afghan border's southern segment over the weekend.
On Saturday, border guards on both sides clashed in the area between Iran's Sistan and Balouchestan province and Afghanistan's Nimruz, resulting in one casualty on each of the sides.
