The warrant was issued by a judge in Baghdad's investigative court tasked with probing the Washington-directed drone strike that killed Gen. Qassim Soleimani and Abu Mahdi al-Muhandis, the court's media office said. They were killed outside the capital’s airport last January.
Soleimani headed the expeditionary Quds force of Iran’s Revolutionary Guard Corps.
The arrest warrant was for a charge of premeditated murder, which carries the death penalty on conviction. It is unlikely to be carried out but symbolic in the waning days of Trump's presidency.
The decision to issue the warrant "was made after the judge recorded the statements of the claimants from the family of Abu Mahdi al-Muhandis,” according to a statement from the Supreme Judicial Council. The investigation into the killings is ongoing, the court said.
The killings sparked a diplomatic crisis and strained U.S.-Iraq ties, drawing the ire of Shiite political lawmakers who passed a non-binding resolution to pressure the government to oust foreign troops from the country.
Iran-backed groups have since stepped up attacks against the American presence in Iraq, leading to threats by Washington to shutter its Baghdad diplomatic mission.
