Hengaw Human Rights Organization, a Kurdish rights group, says the Iranian regime is "transferring heavy and semi-heavy weapons" to the Kurdish-majority regions.

"The Islamic Republic has completely militarized Kordestan,” said Hengaw in a tweet on Sunday, warning of what it called the "consequences of the military movements of the Islamic Republic in Kordestan province".

According to unofficial reports, the Islamic Republic's deadline for the authorities of the Kurdistan Region of Iraq to disarm the opposition groups of the Islamic Republic is coming to an end and if the Iranian authorities are not satisfied with the actions, there might be a new round of attacks against these groups based in northern Iraq.

In March, Ali Shamkhani, the then Secretary of Iranian Supreme National Security Council, signed a security agreement with Iraq during his trip to the Arab country to end the activities of the opponents of the Islamic Republic in the Kurdistan Region.

Two months before that, Ali Khamenei, the Supreme Leader, in a meeting with the Iraqi Prime Minister Mohammed Shia Al-Sudani in Tehran said "Unfortunately, this is happening in some areas of Iraq, and the only solution is for the central government of Iraq to exercise its authority in those areas as well".

Since October last year, the IRGC has bombed the positions of Kurds opposing the Islamic Republic in the autonomous region of Iraqi Kurdistan on several occasions.

These attacks came as Tehran accused Kurdish opposition groups of inciting nationwide protests in Iran.
