Hundreds of angry protesters attacked the Iranian consulate in western Herat province on Sunday over the execution of Afghan nationals in Iran, local officials said.
A peaceful demonstration began around 11:00AM but it turned violent with protesters attacking the Iranian consulate building and inflicting some damage, provincial security police chief of Herat Abdul Hamid Hamidi told TOLOnews.
"It's our responsibility to protect the council. All the members of the council were safe," he said.
"We don't have any problem with a peaceful protest, but they turned to violence," he added.
Some police officers were injured in the attempt to contain the protest.
The protesters were demonstrating against Iran over the killing of Afghan nationals and asked for the "bodies of the executed" to be returned.
Reports said that the demonstration took place after Iranian officials had refused to hand over the dead bodies.
The protesters said that the Iran has executed at least 13 Afghan nationals in the last three months and added that most of them were teenager boys who had gone to Iran for work.
