A leader in Shia leader Muqtada al-Sadr's movement was shot dead in southern Iraq on Tuesday, according to an Iraqi police officer.
Unidentified gunmen opened fire on Rami al-Shabani in al-Diwaniyah city, killing him instantly, police captain Jamal al-Din al-Sudairy told Anadolu Agency.
No group has yet claimed responsibility for the assassination.
Al-Sudairy said an investigation has been launched into the killing.
There was no comment from the Sadrist movement on the attack.
Al-Shabani was a leader in the Peace Brigade, affiliated with the Sadr movement. The Brigade is a member of the pro-government Hashd al-Shaabi, or the Popular Mobilization Forces.
Tuesday's killing came days before the first anniversary of the death of Iranian general Qasem Soleimani in a US drone airstrike in Iraq, amid fears of a surge in attacks on US targets by Iran-backed Iraqi militias.
