Amirabdollahian made the comments during a visit on Thursday to Iran’s southeastern border province of Sistan and Baluchestan, where he is scheduled to follow up on the case of Iran’s water rights, which have long been at the center of a dispute with Afghanistan.

He said based on the 1973 treaty between Iran and Afghanistan, the people of Iran’s Sistan and Baluchestan have “a natural right” to benefit from the water that flows into the country from Afghanistan, and that Tehran would “pursue this with seriousness.”

“If necessary, pressure tools will be used against that part of Afghanistan’s ruling body that refuses to go along with the granting of water rights to Iran,” he added.

Taliban officials recently claimed that due to low water levels, even if they opened the dam, nothing would reach Iran.
