Afghan officials says Taliban militants have killed six police officers who were guarding one of the country's main irrigation dams in the southwest province of Nimruz.
Local police in Nimruz's Chahar Bolak district, where the Kamal Khan dam is located, say three other security officers were wounded as a result of the October 23 attack.
In Kabul, President Ashraf Ghani's office described the incident as a "terroristic attack."
The Kamal Khan dam, located close to Afghanistan's border with Iran, has been a source of tension between Tehran and Kabul.
In 2017, Ghani announced that the days of free-flowing water between the two countries were over.
Since then, Afghan officials have accused Tehran of trying to sabotage the construction of the dam's third phase -- including the use of Taliban militants to try to undermine the project.
The attack at the dam came the same day that at least 23 Afghan soldiers were killed when Taliban militants overran their outpost in Nimruz Province.
Meanwhile, in Ghazni Province on October 24, local officials say nine people were killed when a minibus they were traveling in struck a roadside bomb.
That bomb had been planted on the Kabul-Ghazni highway close to the provincial capital. Authorities said the Taliban was responsible.
