Iraqi authorities have announced a timeline to reopen three crossings with Iran, a day after closing them following a drone attack originating from their shared border on a Saudi pipeline, AFP reports.

After the Friday night attack on the East-West pipeline, Baghdad sacked the military commander in Missan province near the Iran border, after authorities determined the drones were launched from there.

The government then closed three crossings, citing the need to reorganise operations and boost intelligence efforts to stop violations.

The government’s security media cell says that “after reviewing operations at the border crossings,” they would gradually reopen for passengers and trade on a timeline from Sunday until Thursday.

The crossings are Shalamsheh in Basra, al-Shib in Missan, and al-Mandali in Diyala.

Shalamsheh and al-Shib reopened to passengers on Sunday but not to trade, the government media cell has said.
