Hassan Mansour said there would be no further attacks on the Shiite militias until they have completed their work in Syria, Lebanon, Iraq and around the world.

On Saturday night, a spokesman for Iran’s foreign ministry said Iranian diplomats in Iraq were working on forming “a mechanism for protecting Iranian diplomats in Iraq,” the semi-official ISNA news agency reported.

The spokesman did not explain what such a mechanism might look like. Iran’s parliament will convene later this week, possibly to debate if a joint committee should be formed that would allow Iran to intervene in Iraq without Iraqi permission in some cases.

The Iranian parliament would choose the minister of foreign affairs to lead the joint committee and appoint a head of the Iranian liaison office to oversee the initiative, Iranian lawmakers in parliament told Reuters.

Shiite militias have also been working to improve relations with other countries. They have established dialogue with Iraq’s main Arab and Turkmen factions, including the political wing of the Iran-backed Lebanese Hezbollah movement, with which Iran fought a three-year war in neighboring Lebanon. They also work with groups around the world that want to see an end to Syrian President Bashar al-Assad.

While much of this has been welcomed by Sunni and Kurdish parties in the Iraqi parliament, Shiite militias still face discrimination against them in some areas and in some areas are not allowed to defend against Sunni attacks.
