Amid the tensions between Iran and the Taliban over water, the militant group has reportedly deployed a convoy of tanks from Herat to Islam Qala on the border with Iran.

Videos shared on social media show that the Taliban forces are stationed in the region with heavy military equipment.

A video shows a convoy of Taliban tanks moving from Herat towards the Iranian border.

Local sources say the recent tensions between Iran and the Taliban started after they prevented the construction of a road and the installation of barbed wire by the border guards of the Islamic Republic of Iran.

The sources also added that the border forces of the Taliban and border guards of Iran got into a verbal tension last Friday in Islam Qala.

However, the Iranian media wrote on Tuesday evening that the situation at the border is calm.

Tasnim news agency, affiliated with the IRGC, denied any tension between the Taliban and the border guards of the Islamic Republic in the area.

The Taliban authorities have not yet officially commented on sending troops to the border.

The tension at Islam Qala comes as the Taliban and the Iranian border guards clashed on Saturday in Nimroz. Two Iranian guards and one Taliban fighter were killed after shooting broke out near a border post.

It was not immediately clear what had caused the incident, in which several people were also injured, but it came amid tensions over water rights.

Iran has accused Afghanistan's Taliban of violating a 1973 treaty by restricting the flow of water from the Helmand River to Iran's parched eastern regions, an accusation denied by the Taliban.
