ERBIL, Kurdistan Region of Iraq – Iraq on Sunday announced a schedule to resume operations at border crossings with Iran, with traveler entry already resumed at two crossings and commercial activity set to restart at all three by Thursday, a day after Baghdad closed them for security investigations.

On Saturday, Baghdad announced the closure of a number of border crossings with Iran to investigate reported “breaches and violations,” following drone strikes launched from Iraqi territory targeting Saudi Arabia.

Iraq’s Security Media Cell in a statement announced that a “schedule has been established for the resumption of operations at the Al-Shalamja, Al-Mandali, and Al-Shib border crossings,” at the directive of Prime Minister Ali al-Zaidi.

According to the schedule, traveler entry through the Al-Shib border crossing in Maysan province and Al-Shalamja in Basra were resumed at 6:00 am on Sunday, while commercial trade operations will resume at Al-Shalamja on Monday and at Al-Shib on Thursday.

In addition, commercial trade operations will resume at the Al-Mandali in Diyala on Tuesday.

“We also confirm that commercial transit operations with the neighboring side have not ceased and continue around the clock at the Zurbatiyah and Al-Munthiriya crossings,” the statement added.

State media reported Saturday that the Al-Shib and Al-Shalamjah crossings were closed amid the dispatch of a high-level security committee in the area to investigate “security breaches.” Mandali border crossing was also closed, according to Iraq’s border ports authority.

The measures come after several drones were launched from Iraq at Saudi Arabia’s East-West pipeline in the Riyadh and Madina regions on Thursday, according to an announcement by Saudi Arabia’s foreign ministry.

In response, Zaidi directed an investigation into the attack and removed the commander of Maysan’s operations from his post following confirmation that the attacks targeting Saudi Arabia originated from the province.

He also ordered the dismissal of the police chief in Maysan and the transfer of security service directors in the province to the command, referring them for investigation, according to a statement from his office.

Later, government spokesperson Sabah al-Numan said in a statement that Zaidi "agreed to the Iranian side’s request" for a joint investigation into the discovery of drone launch platforms near the Iraqi-Iranian border.
