Iraqi Prime Minister Ali al-Zaidi on Saturday agreed to an Iranian request for a joint investigation into the drone launch sites near the border between the two countries.
The joint mission was confirmed by Sabah al-Numan, spokesman for the Commander-in-Chief of the Iraqi Armed Forces, in a statement carried by the Iraq News Agency (INA).
The statement did not provide further details about the number or locations of the drone launch platforms, nor who was suspected of using them. IT also did not link the new mission to the recent attacks on Saudi Arabia's East-West pipeline, which Iraq's government previously confirmed came from Maysan province, bordering Iran.
In related developments, al-Zaidi made changes to high-ranking security positions in Maysan province, amid regional and international condemnation of the attacks on Saudi Arabia. The prime minister ordered the dismissal of the Maysan operations commander and established an investigative committee to examine the operations command.
No group has taken responsibility for the attacks, including the Islamic Resistance in Iraq, which denied involvement.
Riyadh has said it will not retaliate "at this stage", agreeing to a request from Baghdad to allow time for Iraq to take measures to prevent a repeat of the attacks.
Last July, Saudi Arabia accused Iraqi forces of attempting to target its oil facilities with drones, leading Baghdad to announce it had launched an investigation into the matter.
