Two unidentified gunmen killed the local commander of the Iranian Basij militia in Khuzestan province early on Wednesday, Iran's official news agency IRNA reported.
Abdolhossein Mojaddami, the Basij commander of the Arab-populated southwestern city of Darkhovin, was shot and killed at his home by assailants on motorcycles.
The Basij are a volunteer militia which falls under the command of the Islamic Revolutionary Guards Corp (IRGC).
Director of public relations office of the IRGC in Khuzestan, Mohammad Reza Nemati, said that the attackers fired four bullets at Mojaddami, according to IRNA.
Mojaddami's murder comes almost 3 weeks after IRGC's Quds Force commander Qassem Soleimani's killing by US airstrikes targeting him in Baghdad.
Mojaddami had fought in Syria and was close to Soleimani, according to Iran’s semi-official YJC news agency.
